Question
Use 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: µ2 8300; a = 0.05 Sample statistics: x= 8000, s= 450, n = 24
What are the null and alternative hypotheses?
O B. H,: µ= 8300
H u+8300
O A. H,: µ# 8300
H u= 8300
OC. H.: µs8300
H: u> 8300
O D. H,: µ2 8300
H µ<8300
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?
P=(Round to three decimal places as needed.)
Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below.
O A. Reject Ho. At the 5% level of significance, there is not enough evidence to reject the claim.
O B. Reject Ho. At the 5% level of significance, there is enough evidence to reject the claim.
O C. Fail to reject Ho. At the 5% level of significance, there is enough evidence to reject the claim.
O D. Fail to reject Ho. At the 5% level of significance, there is not enough evidence to reject the claim.
