A sample mean, sample size, and population standard deviation are provided below. Use the one-mean z-test to perform the required hypothesis test at the 5% significance level. x? = 29, n = 14, ? = 7, H0: ? = 25, Ha: ? > 25 Click here to view a partial table of areas under the standard normal curve. The test statistic is z = 2.14. (Round to two decimal places as needed.) The P-value is 0.0162. (Round to four decimal places as needed.) Reject the null hypothesis. The data provide sufficient evidence to conclude that the mean is greater than 25.
