Test the claim about the population mean, μ, at the given level of significance using the given sample statistics.
Claim: μ ≠ 7000; α = 0.08; σ = 396. Sample statistics: x̄ = 7400, n = 40
Identify the null and alternative hypotheses. Choose the correct answer below.
A. H0: μ ≤ 7000, Ha: μ ≠ 7000
B. H0: μ ≥ 7000, Ha: μ ≠ 7000
C. H0: μ ≠ 7000, Ha: μ = 7000
D. H0: μ ≠ 7000, Ha: μ ≥ 7000
E. H0: μ = 7000, Ha: μ ≠ 7000
F. H0: μ ≠ 7000, Ha: μ ≤ 7000
Calculate the standardized test statistic.
The standardized test statistic is
(Round to two decimal places as needed.)
