Listed in the accompanying table are heights (in.) of mothers and their first daughters. The datapairs are from a journal kept by Francis Galton. Use the listed paired sample data, and assumethat the samples are simple random samples and that the differences have a distribution that isapproximately normal. Use a 0.05 significance level to test the claim that there is no difference inheights between mothers and their first daughters.Mother 64.0 66.0 63.0 62.0 66.5 66.0 65.0 60.0 67.0 63.0Daughter 67.0 66.5 70.5 66.0 61.0 66.0 65.5 65.0 67.0 65.0In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the daughter's height minus the mother's height.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm: 142 140 119 132 135 Left arm: 179 170 186 144 140

The average house has 11 paintings on its walls. Is the mean larger for houses owned by teachers? The data show the results of a survey of 14 teachers who were asked how many paintings they have in their houses. Assume that the distribution of the population is normal. 12, 13, 12, 12, 12, 11, 13, 12, 13, 11, 10, 12, 11, 13 What can be concluded at the a = 0.05 level of significance? a.

The "Freshman 15" refers to the belief that college students gain 15 lb (or 6.8 kg) during their freshman year. Listed in the accompanying table are weights (kg) of randomly selected male college freshmen. The weights were measured in September and later in April. Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. Complete parts (a) through (c). = 0 kg Ho: Ha H₁: Hd > 0 kg (Type integers or decimals. Do not round.) Identify the test statistic. t = 2.82 (Round to two decimal places as needed.) Identify the P-value. a. Use a 0.05 significance level to test the claim that for the population of freshman male college students, the weights in September are less than the weights in the following April.
