A sample of 20 from an approximately normal population is used to test . If the value of this test is 0.0132, which of the following is the correct decision and conclusion at the 5% significance level?

Step 1
The null hypothesis, denoted as H0, is the statement that there is no significant difference between the sample mean and the population mean. The alternative hypothesis, denoted as Ha, is the statement that there is a significant difference between the sample mean Show more…

The following sample was taken from a normally distributed population with a known standard deviation σ = 4. Test the hypothesis that the mean μ = 20 using a level of significance of 0.05 and the alternative that μ > 20: 23, 32, 22, 31, 27, 25, 21, 24, 20, 18.

A random sample of five resulted in the following values: 18, 15, 12, 19, and 21. Assume a normal population. Using the 0.01 significance level, can we conclude the population mean is less than 20? Identify the hypotheses, number of tails, the type of test, the test stat, the critical value(s), the decision, and the conclusion.

Which of the following is a valid decision for a test conducted at the 5% significance level? Because the p-value is not less than 0.05, we fail to reject the null hypothesis. Because the p-value is not less than 0.05, we accept the null hypothesis. Because the p-value is less than 0.05, we accept the null hypothesis. Because the p-value is less than 0.05, we fail to reject the null hypothesis.
