For each of the following situations, calculate the p-value and determine if H₀ is rejected at a 5% significance level with the test statistic, -1.75. All numbers should be reported to four decimal places.

a) Consider a hypothesis test concerning a population mean with σ known and n = 500.

(0.3 pts.) H₀: μ = 693 H_a: μ < 693
p-value: ?

Will H₀ be rejected in part a)?

b) Consider a hypothesis test concerning a population mean with σ unknown and n = 61.

(0.3 pts.) b) H₀: μ = 288 H_a: μ ≠ 288

p-value: ?

Will H₀ be rejected in part b)?

For a test of a mean, which of the following is correct? Top of Form H0 is rejected when the calculated p-value is less than the specified level of significance For a left-tailed test, the null hypothesis H0 will be rejected when the test statistic exceeds the critical value . The test statistic value is based on the chosen level of significance. If H0: μ= 5 and H1: μ ≠ 5, then the test can either be a right-tailed test...
