Use technology and a t-test to test the claim about the population mean u 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, n3 28
What are the null and alternative hypotheses? Choose the correct answer below.
A. Ho: HS79
O B. Ho: H2 79
Ha H<79
Ha: µ >79
O D. Ho: H= 79
HA: H+79
O C. Ho: H#79
Ha: H = 79
What is the value of the standardized test statistic?
The standardized test statistic is 2.92. (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.)
