A random sample of 15 families representing three social classes has been observed for the frequency with which the parents administer physical punishment to the children over a period of a week. Are the differences significant? Use α = .05 and the five-step model to conduct your hypothesis test. Write a sentence or two interpreting your results.

General Motors and Ford have produced cars with the same size diesel engin in determining whether or not there is a significant difference in the gas consumption of the two models of automobiles. A random sample of 7 cars from each manufacturer is selected, and 7 drivers are selected to drive one of GM and one of Ford cars for a specified distance implying that driver 1 drove the first GM car and the first Ford car, driver 2 drove the second GM car and the second Ford car, driver 3 drove third GM car and the third Ford car, and so on. The MPG (miles per gallon) data is recorded and summarized in the following table: Driver 1 2 3 4 5 6 7 General Motors Model (MPG) 29 25 26 25 22 24 27 A Ford Model (MPG) 26 23 27 25 24 23 25 Which of the following is a correct statement if the objective of the test of hypothesis is to determine whether there is a difference in the gas consumption of the two models? Select one: O A. Ho: HGM = Ford OB. Ho: D=0 (where D is the mean population difference)

The average price per square foot for a home in a large county in a certain state is $225. The council of a country town wonders if the mean price of the homes in their town is less than the mean price of the homes in the county. The town council selected a random sample of 9 homes that have recently sold in their town. They found the price per square foot and want to perform a hypothesis test at the α=0.01 significance level. The data is listed below. 221.4 213.1 219.1 229.6 220.7 224.4 221.6 217.8 223.9 1.

A new beta-blocker medication is being tested to treat high blood pressure. Subjects with high blood pressure volunteered to take part in the experiment. 160 subjects were randomly assigned to receive a placebo and 290 received the medicine. High blood pressure disappeared in 80 of the controls and in 159 of the treatment group. Test the claim that the new beta-blocker medicine is effective at a significance level of a = 0.01.What are the correct hypotheses?H0: p1 = p2 H1: p1< p2 Based on the hypotheses, find the following:Test Statistic = ?p-value = ?The test statistic is: not critical to the regionThe correct decision is to fail to reject the null hypothesisThe correct summary would be: there is not enough evidence to support the claim that the new beta-blocker medicine is effective at a significance level of a = 0.01.
A researcher believes that the percentage of people who exercise in California is greater than the national exercise rate. The national exercise rate is 20%. The researcher gathers a random sample of 120 individuals who live in California and finds that the number who exercise regularly is 31 out of 120. Please use the chi-square test to design a complete hypothesis testing process and get appropriate conclusions. (You need to indicate the value of X2obt and df and X2cv)
A legal researcher was interested in gender differences in the willingness of prosecutors to plea bargain. She recorded the number of times they plea bargained out of their last 10 cases for a sample of eight female prosecutors and seven male prosecutors. Table 2 shows the number of plea bargain cases by gender Table shows the number of plea bargain cases by gender Females Males 9 4 3 5 5 7 9 4 9 3 5 4 7 3 5 From performing a hypothesis test at alpha = .05 level to determine if female and male prosecutors differ in their plea bargaining of cases, complete the sentence: The p value is [w] than alpha. Consequently [x] hypothesis is [y]; thus there is [z] in average levels of intelligence between the two.
You are a manufacturing engineer with a machine company. The company buys 55 gallon drums of pentrating lubricant. These drums are expensive. The weight of a drum should be 400 pounds. As a new engineer you have been asked to use your Six Sigma Green Beit to determine if these barrels really weigh 400 pounds. Your company knows statistics and has asked you to use a hypothesis test at the 5% level of significance. You select 9 barreis at random and weigh. You find the average weight of the barrels to be 398 pounds with a standard deviation of 22 pounds. Answer the following Your null hypothesis is equal to what? (no decimals) What is the hypothesis test? (greater than or less than) What is your sample size? (no decimal) What is your sample mean? (no decimal) What is your sample standard deviation?
