Question 25

 

Test the claim about the population mean μ at the level of significance α. Assume the population is normally distributed.
Claim: μ ≥ 1474; α = 0.09; o = 27. Sample statistics: x= 1465, n = 28
Identify the null and alternative hypotheses. Choose the correct answer.
Ο Α. Ηο: με 1474
Ha:μ< 1474
OC. Ho: μ> 1465
H₂:μ≤ 1465
O E. Ho: μ< 1465
Ha:μ ≥ 1465
Calculate the standardized test statistic.
The standardized test statistic is
(Round to two decimal places as needed.)
Determine the P-value.
P= (Round to three decimal places as needed.)
Determine the outcome and conclusion of the test.
Ho. At the 9% significance level, there
enough evidence to
▼the claim.
OB. Ho: μ> 1474
Ha:μ≤1474
O D. Ho: μ< 1474
Ha:μ²1474
OF. Ho:μ ≥ 1465
Ha: μ< 1465
