A medical researcher wishes to determine if a pill has the undesirable side effect of reducingthe blood pressure of the user. The study involves recording the initial blood pressures of 15college-age women. Suppose the data are normally distributed. After they use the pill regularlyfor six months, their blood pressure are again recorded. The data is given bellow.Subject1234567 8Before 70 8072 76 76 7672 789 10 11 12 13 14 1582 64 74 92 74 68 8464 72 74 60 74 72 74After 68 72 62 70 58 66 68 52(a) Calculate a 95% confidence interval for the mean reduction in blood pressure.(b) Does the data support a claim that use if the pill can reduces blood pressureby using one-tailed test at level a = 0.01.

A federal regulatory agency is investigating an advertised claim that a certain device can increase the gasoline mileage of cars (mpg). Ten such devices are purchased and installed in cars belonging to the agency. Gasoline mileage for each of the cars is recorded both before and after installation. The data are recorded here.

What type of test is this? How many degrees of freedom? What is the absolute value (positive) of the test statistic in step 4 to 2 decimal places? Find the p-value to 4 decimal places. Should you reject the null at 5%? Find the margin of error for a 95% confidence interval on the difference in means to two decimal places. 3.

A psychologist believed that as children get older, they engage in more “inactive activities” such as playing computer games, watching TV and surfing the internet. She collected data from 10 children. She recorded the age of each child and the amount of activity (in hours) the child engaged in per week. Age Activity 7 4.3 9 3.2 10 1 13 1.5 12 1.2 15 0.8 9 3 12 4 15 1.5 14 1.9 Using excel, obtain a scatterplot of the data. Discuss the relationship between age and activity based on the scatterplot. Using excel, obtain the simple linear regression linear regression line predicting activity from age. Interpret the intercept and slope of the regression line. By hand, predict the amount of activity for age = 14. By hand, calculate the residual for age = 14 Using excel output, test the null hypothesis that the slope coefficient is zero using the p-value approach. Write one sentence interpreting the meaning of this result. Make sure to report the test statistic…
Section 9.3 Question #3 The following data lists the ages of a random selection of actresses when they won an award in the category of Best Actress, along with the ages of actors when they won in the category of Best Actor. The ages are matched according to the year that the awards were presented. Complete parts (a) and (b) below. Actress (years) 25 25 33 26 32 26 26 45 28 35 Actor (years) 66 41 40 41 30 33 53 40 34 39 a. Use the sample data with a 0.05 significance level to test the claim that for the population of ages of Best Actresses and Best Actors, the differences have a mean less than 0 (indicating that the Best Actresses are generally younger than Best Actors). In this example, μd 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 actress's age minus the actor's age. What are…
