Question
USt to test the claim about the population mean p at the given level of significance a using the given sample statistics. Assume the popula
normally distributed.
Claim: u>72; a= 0.10 Sample statistics: x= 74.3, s= 3.4, n 28
What are the null and alternative hypotheses? Choose the correct answer below.
O A. Ho H272
HA H<72
O B. H, p=72
HA u#72
O C. H, µ572
HA H>72
O D. H, µ#72
HA u=72
What is the value of the standardized test statistic?
The standardized test statistic is. (Round to two decimal places as needed.)
What is the P-value of the test statistic?
P-value =(Round to three decimal places as needed.)
