On average, Americans have lived in 4 places by the time they are 18 years old. Is this average a different number for college students? The 50 randomly selected college students who answered the survey question had lived in an average of 3.79 places by the time they were 18 years old. The standard deviation for the survey group was 1.2. What can be concluded at the α = 0.10 level of significance?
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the average is a different number for college students
Step-by-step explanation:
From the question we are told that
The sample size is n = 50
The population mean is [tex]\mu = 4[/tex]
The sample mean is [tex]\= x = 3.79[/tex]
The standard deviation is [tex]\sigma = 1.2[/tex]
The level of significance is [tex]\alpha = 0.10[/tex]
The null hypothesis is [tex]H_o : \mu = 4[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 4[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x - \mu }{ \frac{ \sigma }{ \sqrt{n}} }[/tex]
=> [tex]z = \frac{ 3.79 - 4 }{ \frac{1.2}{ \sqrt{50}} }[/tex]
=> [tex]z = -1.237[/tex]
From the z table the area under the normal curve to the left corresponding to -1.237 is
[tex]P(Z < -1.237) = 0.10804[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(Z < -1.237) = 2 * 0.10804[/tex]
=> [tex]p-value = 0.21608[/tex]
Generally from the values obtained we see that
[tex]p-value > \alpha[/tex]
Hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to conclude that the average is a different number for college students

Mrs. Rogers sold 49 out of 78 crafts at the fair. What percent of her crafts did she sell? Please show work!
Answer:
62 32/39%
Step-by-step explanation:
[tex]\frac{49}{78}*\frac{100}{1}=\frac{4900}{78}=\frac{2450}{39}=62\frac{32}{39}%[/tex]%
The percentage of Mrs. Rogers crafts sold is 62.82%.
Given that, Mrs. Rogers sold 49 out of 78 crafts at the fair.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Percent of crafts sold =Number of crafts sold/Total number of crafts ×100
= 49/78 ×100
= 0.6282×100
= 62.82%
Therefor, the percentage of Mrs. Rogers crafts sold is 62.82%.

The kinetic energy of an object is described with the formula K = v2 where K is the kinetic energy of the object in joules (J). m is the mass of the object in
kilograms (kg), and v is the velocity of the object in meters per second (w). What is the velocity of an object with a kinetic energy of 375 J and a mass of 50
kg?
Answer:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of

Best answer gets a brainiest Joe and his family are touring Chicago. They want to visit the Willis Tower, hang out at Navy Pier, and shop on Michigan Avenue before their dinner reservations at 5:10 P.M. They plan to spend 1 hour and 10 minutes at the Willis Tower, 3 hours and 10 minutes at Navy Pier, and 1 hour and 15 minutes shopping. What is the latest time Joe's family can start their tour of Chicago and still make it to dinner on time?
Include A.M. or P.M. in your answer
Answer:
11:35 am
Step-by-step explanation:
1 hour and 10 minutes at the Willis Tower,
3 hours and 10 minutes at Navy Pier
1 hour and 15 minutes shopping
Total time: 5 hours 35 minutes
They need to be at dinner at 5 :10 pm
Subtract 5 hours
12:10 pm
Subtract 35 minutes
Subtract 10 minutes makes 12:00pm
Then go back 25 more minutes
11:35 am
y is inversely proportional to the cube of x if y = 7 when x=4 what is y when x is 5
Answer:
y = 3.584
Step-by-step explanation:
Given
Variation = Inverse Proportional
When y = 7, x = 4
Required
Find y when x = 5
First, we need to represent the variation.
y varies inversely proportional to x³
This implies that
y ~ 1/x³
Convert variation to equation
y = k/x³
Make k the subject
k = x³y
When y = 7, x = 4
This gives:
k = 4³ * 7
k = 64 * 7
k = 448
To determine the value of y when x = 5;
We make use of y = k/x³
Substitute 5 for x and 448 for k
y = 448/5³
y = 448/125
y = 3.584

write the number with the least value using the digits 1 through 9. use each digit only once. explain your reasoning
Answer: 123456789
Step-by-step explanation:
We need to write a 9-digit number using the digits 1, 2, 3, 4, 5, 6, 7, 8, and 9.
(where we can use each digit only one time)
We want the value of this 9-digit to be the smallest as possible, then:
The largest single value digit (9), needs to be in the smallest value place (in the units place)
The second larger digit (8), must be in the second smallest value place (in the tens)
And so on, then the 9-digit number will be something like:
123456789
Any other permutation will be larger than this number.
