Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x=97.78, y = 96.9, r=0.830, P-value = 0.000, and y = 20.49 +0.78x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 91? Use a significance level of 0.05. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted value of ŷ is. (Round to two decimal places as needed.)
Suppose that Dietitians recently recommended a 400 cal per meal and take her children of the age of the data set. To see if both groups adhere to the guideline follow the steps to develop and test a statistical hypothesis. Test to see if us groups means are different from 400 calories. You have two data sets so you'll be completing the process twice. Use 0.05 as a level of significance and make sure to report any important statistic with your results (e.g., mean of each group, standard deviation of each group, test stastistic (are you using t or z?), rejection region and p value).

The table below summarizes data from a survey of a sample of women. Using a 0.01 significance level, and assuming that the sample sizes of 800 men and 300 women are predetermined, test the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. Does it appear that the gender of the interviewer affected the responses of women? Compute the test statistic. (Round to 3 decimal places) Find the critical value(s). (Round to 3 decimal places. Use a comma to separate answers as needed.) What is the conclusion based on the hypothesis test? ▼ (Fail to reject/Reject) H0.There ▼ (is not/ is) sufficient evidence to warrant rejection of the claim that the proportions of agree/disagree responses are the same for subjects interviewed by men and the subjects interviewed by women. It ▼ (does not appear/ appears) that the gender of the interviewer affected the responses of women.
In a fishing lodge brochure, the lodge advertises that 75% of its guests catch northern pike over 20 pounds. Suppose that last summer 65 out of a random sample of 78 guests did, in fact, catch northern pike weighing over 20 pounds. Does this indicate that the population proportion of guests who catch pike over 20 pounds is different from 75% (either higher or lower)? Use ? = 0.05. -What is the value of the sample test statistic? (Round your answer to two decimal places.) -What is the value of the sample test statistic? (Round your answer to two decimal places.)
Road Transport Department claims that the mean speed of cars on a highway is 114 km/h. An insurance company took a random sample of 21 cars driven on a highway and found that the test statistic is -2.2913. Can we accept the Road Transport Department's claim at 5% level of significance?

Suppose IQ scores were obtained for 20 randomly selected sets of siblings. The 20 pairs of measurements yield x = 101.13, y = 103.5, r=0.867, P-value = 0.000, and y = 6.25 +0.96x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 101? Use a significance level of 0.05.
