Determine the p-value of the test statistic
WebSince the calculated value of the test statistic from the sample is positive, calculate an upper-tailed p-value. When the calculated value of the test statistic from the sample is negative, calculate a lower-tailed p-value and in step 5 enter K2 in Optional storage. Click OK. This value is the p-value for a one-tailed test. WebThe summary statistics are n = 189, x = 6.59, s=2.07. Use a 0.10 significance level to test the claim that the population mean of such ratings is less than 7.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original ...
