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, -1.94. All numbers should be reported to four decimal places. a) Consider a hypothesis test concerning a population mean with σ known and n = 1300. As stated above the test statistic is -1.94. H0: μ = 656 Ha: μ < 656 i) What is the p-value? ii) Will H0 be rejected in part a)? iii)...

To test H0: mean = 80 vs. H1: mean < 80, a simple random sample of size n = 22 is obtained from a population that is known to be normally distributed. (a) If x-hat = 76.9 and s = 8.5 compute the test statistic (b) If the researcher decides to test the hypothesis at the a = 0.02 level of significance, determine the critical value. (c) Draw a t-distribution that depicts the critical region (d) Will the researcher reject...

A researcher is interested in testing the hypothesis H0 : μ = 8 vs H1 : μ > 8, using a sample of size 81. The population standard deviation is known to be σ = 5. The researcher decides to reject H0 if X ≥ 9. What is the significance level of this hypothesis test? Assume that the population is normal. Express your answer as a decimal (not as a percentage).
