Use technology to help you 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: μ ≤ 1180; α = 0.03; σ = 213.57. Sample statistics: x = 1213.93, n = 200
Identify the null and alternative hypotheses. Choose the correct answer below.
A. H<sub>0</sub>: μ ≤ 1180
H<sub>a</sub>: μ > 1180
C. H<sub>0</sub>: μ ≥ 1213.93
H<sub>a</sub>: μ < 1213.93
E. H<sub>0</sub>: μ ≤ 1213.93
H<sub>a</sub>: μ > 1213.93
B. H<sub>0</sub>: μ > 1180
H<sub>a</sub>: μ ≤ 1180
D. H<sub>0</sub>: μ > 1213.93
H<sub>a</sub>: μ ≤ 1213.93
F. H<sub>0</sub>: μ ≤ 1180
H<sub>a</sub>: μ < 1180
Calculate the standardized test statistic.
The standardized test statistic is 2.25.
(Round to two decimal places as needed.)
Determine the P-value.
P = 0.012 (Round to three decimal places as needed.)
Determine the outcome and conclusion of the test.
Reject H<sub>0</sub>. At the 3% significance level, there is enough evidence to reject the claim.
