Use the following information to answer questions 10-14.
An advertising agency would like to create an advertisement for a
fast-food restaurant claiming that the
average waiting time from ordering to receiving your order at the
restaurant is, on average, 5 minutes.
The agency measured the time from ordering to deliver of order for
25 customers and found that the
average time was 5.3 minutes with an SD+ of .6 minutes. Is this
evidence that the waiting time is more
than 5 minutes, or could this result be due to chance?
10. Choose the appropriate null and alternate hypotheses for this
problem.
a. Null: The average wait time is 5.3 minutes.
Alternate: The average wait time is less than 5.3 minutes.
b. Null: The average wait time is 5 minutes.
Alternate: The average wait time is more than 5.3 minutes.
c. Null: The average wait time is 5 minutes.
Alternate: The average wait time is more than 5 minutes.
d. Null: The average wait time is 5 minutes.
Alternate: The average wait time is less than 5.3 minutes.
11. What is the test statistic?
a. -3.03
b. 2.50
c. 0.50
d. 5.30
12. Enter the degrees of freedom.
13. Enter the p-value.
a. 0.01%
b. 0.98%
c. 31.07%
d. 2.35%
14. What is your conclusion?
a. Reject the null hypothesis
b. Accept the null hypothesis
c. Do not reject the null hypothesis
d. Do not accept the alternate hypothesis

A public bus company official claims that the mean waiting time for bus number 14 during peak hours is less than 10 minutes. Karen took bus number 14 during peak hours on 18 different occasions. Her mean waiting time was 9 minutes with a standard deviation of 2.9 minutes. At the 0.01 significance level, test the claim that the mean waiting time is less than 10 minutes. - Identify the null hypothesis and alternative hypothesis - Identify the test statistic...
