She records the height of both the father and son in inches and obtains the following data. Are sons taller than their fathers? Use the a=0.025 level of significance. Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. P. Click the icon to view the table of data. . Х Table of height data .. Which conditions must be met by the sample for this test? Select all that apply. A. The sampling method results in a dependent sample. B. The sampling method results in an independent sample. C. The sample size is no more than 5% of the population size. OD. The differences are normally distributed or the sample size is large. E.

Write the hypotheses for the test. Ho Hai Calculate the test statistic. to-(Round to two decimal places as needed.) ( Calculate the P-value. Print Done P-value = (Round to three decimal places as needed.) Should the null hypothesis be rejected? Ho because the P-value is the level of significance. There sufficient evidence to conclude that sons their fathers at the 0.025 level of significance.
