It is thought that not as many Americans buy presents to celebrate Valentine's Day anymore. A random sample of 40 Americans yielded 22 who bought their significant other a present and celebrated Valentine's Day. Estimate the true proportion of all Americans who celebrate Valentine's Day using a 98% confidence interval. Express the answer in the form the point estimates /- the margin of error.
Answer:
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
(0.3672 , 0.7328)
Step-by-step explanation:
Explanation:-
Given Random sample size n =40
Sample proportion
[tex]p = \frac{x}{n} = \frac{22}{40} = 0.55[/tex]
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
[tex](p-Z_{\alpha } \sqrt{\frac{pq}{n} } , p + Z_{\alpha } \sqrt{\frac{pq}{n} } )[/tex]
The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
[tex](0.55-2.326\sqrt{\frac{0.55 X0.45}{40} } , 0.55 + 2.326\sqrt{\frac{0.55 X0.45}{40} } )[/tex]
( 0.55 - 0.1828 , 0.55 + 0.1828)
(0.3672 , 0.7328)
Answer:
Step-by-step explanation:
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326
98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day
( 0.55 - 0.1828 , 0.55 + 0.1828)

Write the equation of the line with a slope of -1.6 and a y-intercept of 4 in slope-
intercept form.
Answer:
y = -1.6x + 4
Step-by-step explanation:
y = mx + b
y = (-1.6)x + (4)
y = -1.6x + 4
The equation of line with a slope of -1.6 and a y-intercept of 4 in slope- intercept form is,
⇒ y = - 1.6x + 4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
We have to given that;
Slope of the line (m) = - 1.6
And, The y - intercept = 4
We know that;
The slope intercept form of an equation of line is,
⇒ y = mx + b
Where, 'm' is slope of the line and 'b' is y - intercept of the line.
Hence, The equation of line with a slope of -1.6 and a y-intercept of 4 in slope- intercept form is,
⇒ y = mx + b
⇒ y = - 1.6x + 4

Step-by-step explanation:
A restaurant chain with multiple branches would like to measure the effectiveness of a customer skills training program for its employees. A random sample of 30 branches is chosen, and the daily sales for these branches are recorded. All the employees at these branches then undergo a customer skills training program, and shortly thereafter the daily sales at these 30 branches are again recorded. (a) Which type of test should the company use to determine if the customer skills program helped increase sales? a. One sample t-test b. Paired t-test c. Chi-squared test of independence d. One proportion z-test OTwo sample t-test (independent means) (b) A Type II error in this context means the company finds evidence of an increase in sales, when in reality there is in sales.
Answer:
A) Option B: Paired t-test
B) The company finds "SUFFICIENT" evidence of an increase in sales, when in reality there is "A DECREASE" in sales
Step-by-step explanation:
A) Let's look at the options.
a) One sample t-test: This t-test is a statistical hypothesis test that's used to find out whether an unknown population mean has a different value from the sample mean.
b) Paired t-test: This is used to compare mean at different times from the same group.
c) Chi-squared test of independence: This test is one that is used to determine whether the associated variables are related or independent.
d) One proportion z-test: This test is used to compare an observed proportion to that of a theoretical proportion.
e) Two sample t-test: This is used to test if the unknown population mean that is gotten from two groups are equal or not.
Now, from the question, we see that A random sample of 30 branches is chosen, and the daily sales for these branches are recorded.
Later on, All the employees at these branches then undergo a customer skills training program, and shortly thereafter the daily sales at these 30 branches are again recorded.
This means that we are trying to compare the mean within the same group but at different times. This corresponds to the definition of Paired t-test.
B) A Type II error occurs when we accept a null hypothesis that is actually false.
The type II error in this case is that:
The company finds "SUFFICIENT" evidence of an increase in sales, when in reality there is "A DECREASE" in sales

India has a 12-foot board. How many 18-inch pieces can she cut from the board?
Answer:
Step-by-step explanation:
There are 12 inches in a foot
So for one full foot in inches you have just 1 foot with 6 inches remaining/ 1 foot with half a foot remaining.
Hope this helped!
Answer: 8 pieces.
Step-by-step explanation;
There is 12 inch in a foot, so they are 144 inches in 12 foot. If India cuts 18-inch pieces, she can cut 8 pieces. You can find this amount by dividing 144 inches into 18 inches, this will be eight pieces.

help please, i will love you forever
Answer:
See Below
Step-by-step explanation:
I'm not going to do the homework for you, but I will complete three of the problems to help you understand the process.
We are converting between different units of measurement.
Here are the conversions to know:
12 inches = 1 foot
3 feet = 1 yard
1760 yard = 1 mile
5280 feet = 1 mile
#1
We need to convert 7 feet into inches.
7 feet * 12 inches per foot = 84 inches
Now we know:
84 inches = 7 feet
What's the difference is between 84 inches, and 18 inches?
84 inches - 18 inches = 66 inches
We need 66 more inches to get a length of 7 feet.
#2
We need to convert 2 miles into yards.
2 miles * 1760 yards per mile = 3520 yards.
Now we know:
3520 yards = 2 miles
What's the difference between 3520 yards and 2000 yards?
3520 yards - 2000 yards = 1520 yards
We need 1520 more yards to make 2 miles
#3
We need to convert 108 inches into feet.
108 inches / 12 inches per foot = 9 feet
Since there is no remainder,
9 feet = 108 inches.
Hopefully you can see what is going on here and do the rest yourself.
Which answer describes the transformation of g(x)=log2(x+3)+1 from the parent function f(x)=log2x ?
Answer:
g(x) is the function f(x) which is shifted 3 units left and 1 unit upStep-by-step explanation:
Given
g(x)=log2(x+3)+1andf(x)=log2xThe transformation is
g(x) = f(x + 3) + 1, which indicates thatg(x) is the function f(x) which is shifted 3 units left and 1 unit upg(x) is the function f(x) which is shifted 3 units left and 1 unit up
If you are given
g(x)=log2(x+3)+1 and f(x)=log2x
Then the transmission is g(x) = f(x + 3) + 1, which indicates that g(x) is the function f(x) which is shifted 3 units left and 1 unit up

The correct answer is:
A) −12d−15 (None of the options provided are equivalent to the given expression.)
How to determine the equivalentTo simplify the expression −4(3d−2)−7, we can apply the distributive property by multiplying -4 to each term inside the parentheses:
−4(3d−2)−7 = -4 * 3d + (-4) * (-2) - 7
This gives us:
-12d + 8 - 7
Combining like terms:
-12d + 1
So the expression is equivalent to -12d + 1.
Therefore, the correct answer is:
A) −12d−15 (None of the options provided are equivalent to the given expression.)
