Find the p-value for each of these situations. Be sure to take into account whether the test is left sided, right sided, or two sided. Hints: Draw a picture! Also, all provided information may not be relevant. Note that when testing the value of a single population mean (rather than a difference in means), degrees of freedom are df = n - 1. Round all answers to three decimal places a. H0: μ1 - μ2 = 0 HA: μ1 -...
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)...
Find z* for each of these situations, taking into account whether the test is one-sided or two-sided. Then find the p-value, indicating its relation to alpha. Finally, determine if the hypothesis test would lead to rejection of the null. Test statistic(z) = -2.84, Ho : p = .10, Ha : p < .10, α = .06
Find z* for each of these situations, taking into account whether the test is one-sided or two-sided. Then find the p-value, indicating its relation to alpha. Finally, determine if the hypothesis test would lead to rejection of the null. Test statistic(z) = 2.10, Ho: p = .10, Ha : p > .10, α = .05

P-value is the probability, computed assuming H0 is true, that the test statistic would take a value as extreme or more extreme than that actually observed. Given the sample at hand, it is the smallest level of significance at which H0 would be rejected. It depends on the sample (hypotheses as well) and is hence also a test statistic. Generate 50 samples of size n=10 from a normal distribution with mean μ=1 and variance σ2=4. For each sample, use the...
