Use technology and a t-test to test the claim about the population mean p at the given level of significance a using the given sample statistics. Assume the population is normally distributed.
Claim: u>79; a = 0.10 Sample statistics: x= 80.6, s =2.9, n= 28
What are the null and altemative hypotheses? Choose the correct answer below.
A. H;: us79
Ha: u> 79
O B. Ho 279
Ha H<79
OD. Ho: u= 79
Ha u#79
OC. Ho H#79
HA: = 79
What is the value of the standardized test statistic?
The standardized test statistic is
(Round to two decimal places as needed.)
