For each of the following situations, calculate the p-value and determine if H₀is rejected at a 4.8% significance level with the test statistic, -1.81. All numbers should be reported to five decimal places.

(1 points) a) Consider a hypothesis test concerning a population mean with

known and n = 86. As stated above the test statistic is -1.81.

H₀: = 700 H_a: < 700 (find p value, will the null be rejected?) Show work

b. Consider a hypothesis test concerning a population mean with

unknown and n = 46. The value of the test statistic is the same and is -1.81.

b) H₀: = 227 H_a: 227(find p value, will null be rejected)
