Consider the following hypothesis test: Ho: mu<=12 H1: mu>12 A sample of 20 provided a sample mean of 14 and a sample standard deviation s = 4.52 . Use a = 0.05 . Step 1: Calculate the test statistic for this problem . Round your answer to four decimal places. Step 2: What is the p-value for your test? Step 3: State the conclusion to this problem.
A random sample is taken from a normal population. Do the hypothesis test to determine if there is evidence that the population standard deviation is greater than 5. Use a level of significance of α = 0.05. n = 25 xbar = 68.7 s = 6.2 Use the appropriate notation to show the hypotheses. H0: H1: The critical value is _________ = _______________________ The test statistic is __________= ________________________ The p value is __________________________________

Consider the following hypothesis test. H0: ≥ 10 H1: <10 The sample size is 120 and the standard deviation of the population is 5. Use a = 0.05. a. If the real value of the population mean is 9, what is the probability that the mean of the sample will lead us not to reject H0? b. What type of error would be committed if the real value of the population mean was 9 and we conclude...
