4. Heights of Parents. A sociologist claims that women tend to marry men who are taller than themselves? Suppose that 20 random married couples are measured. If the difference in height for each set of parents is found by subtracting the mother's height from the father's height, the mean was 4.4 inches with a standard deviation of 4.2 inches. Use a 0.01 significance level to test the claim that the mean difference is greater than 0.
For the folllwing two questions state the response variable and the explanatory variable 1.Is there a relationship between the final rating given by the customer and the number of exchanges during the conversation? If so, which of the exchange categories have significantly different mean ratings? 2. It is thought that having a relatively consistent length of message in any given conversation indicates a pattern of helpful, well-balanced communication. In fact, some new research suggests that to ensure a productive conversation the maximum message length should be no more than 8 words greater than the minimum message length in any conversation. Test whether the conversations in the sample meet the criteria suggested by this research study.
The prices of a sample of books at University A were obtained by two statistics students. Then the cost of books for the same subjects (at the same level) were obtained for University B. Assume that the distribution of differences is Normal enough to proceed, and assume that the sampling was random. a. First find both sample means and compare them. b. Test the hypothesis that the population means are different, using a significance level of 0.05. E Click the icon to view the table of prices. a. Find the sample mean for University A.

For a population data set, o = 13.7. a. What should the sample size be for a 98 % confidence interval for u to have a margin of error of estimate equal to 5? b. What should the sample size be for a 92 % confidence interval for u to have a margin of error of estimate equal to 3.75? Note: You must round your answer UP to a whole number. For example, 92.1 should be rounded to 93.

In 1908, William Gosset published the article "The probable Error of a Mean" under the pseudonym of "Student". He included the data listed below for two different types of corn seed that were used on ad jacent plots of land. The listed values are the yields of head corn in pounds per acre. Use a 0.10 significance level to test the claim that the mean difference in yield between the two types of seed is 0.
