Question
A bank manager is interested in if the mean time it takes for customers to be
served at their branch is 8 minutes. Having taken a random sample of customer
waiting times, the manager performs a hypothesis test and finds a p-value of
0.03. At the 5% significance level, the conclusion of the test will be:
A.
B.
C.
D.
E.
As only the p-value is provided, there is not enough information to be
able to decide whether to reject or not reject the null hypothesis at the
5% significance level.
The results suggest that, at the 5% significance level, the population
mean waiting time is not 8 minutes.
The results suggest that, at the 5% significance level, the population
mean waiting time is in fact 0.03 minutes.
The results suggest that, at the 5% significance level, the manager is
unable to reject the null hypothesis, that the population mean waiting
time is 8 minutes.
None of the above.
The mean represents:
A. the arithmetic average of a data distribution
B. the degree of kurtosis
C. the most frequently occurring value in a distribution
D. the degree of skewness
E. the midpoint of a data distribution
