(b) For height, the mean difference between the reported height and actual measured height was 0.7 inches and the standard deviation of the differences was 0.9 inches. Carry out a hypothesis test to determine if there is a signicant difference in the mea reported height and the mean actual height for male college students. (Use a = 0.05. Use \"d = \"repoited \"actual') State the appropriate null and alternative hypotheses. O HO: yd = 0 Ha: pd at 0 OHD:ud>0 Hazud=0 Find the test statistic and Pvalue. (Use a table or technology. Round your test statistic to one decimal place and your P-value to three decimal places) t = P-value = State the conclusion in the problem context. 0 We fail to reject H0. There is not a significant difference in the mean reported height and the mean actual height for male college students. 0 We fail to reject H0. There is a signicant difference in the mean reported height and the mean actual height for male college students. 0 We reject H0. There is a significant difference in the mean reported height and the mean actual height for male college students. 0 We reject HO. There is not a signicant difference in the mean reported height and the mean actual height for male college students. (c) Do the conclusions reached in the hypothesis tests of parts (a) and (b) support the given conclusion that male college students tend to over-report both height and weight? Explain. Select--- v resulted in rejecting the null hypothesis. Additionally, the t test statistics are -Seleoi- v , which tells us that the population mean differences are likely to be ~Selectm v for reported value minus actual value. As such, we u-Selectm v convincing evidence that male college students tend to overreport both height and weight. (b) For height, the mean difference between the reported height and actual measured height was 0.7 inches and the standard deviation of the differences was 0.9 inches. Carry out a hypothesis test to determine if there is a signicant difference in the me: reported height and the mean actual height for male college students.
