2. A random sample of receipts for individuals eating at the Terrace Restaurant showed the sample mean to be X $10.39 with sample standard deviations = $2.15. (a) Use Chebyshev's Theorem to find the smallest interval centered on the mean in which we can expect at least 88.9% of the data to fall. (b) If our sample is normally distributed, what interval will contain exactly 95% of our data?

The data set provided in StatCrunch contains a random sample of 47 Craigslist posts for various used Honda Civics. A Mason student is interested in purchasing a used Honda Civic and wants to research what variables influence the price of the used cars: the age of the car or the mileage of the car. They recorded the “Price” in US dollars, the “Age” in years (counting from 2021, thus a 10-year-old car was a 2011 since 2021 – 2011 = 10), and the “Mileage” in thousands of miles. Use the “Mileage” in thousands of miles and “Age” in years to predict the “Price” in US dollars. The student wants to find which explanatory variable, either “Mileage” or “Age”, will be the best predictor of the response variable, “Price”. Investigate the relationship between the explanatory variables and response variable to help the student find the better predictor. -Interpret the scatterplot of “Age” and “Price” using trend, strength, and shape (form) and Interpret the scatterplot of “Mileage” and “Price” using…

Some research has shown that older parents are not as strict when disciplining their children compared to younger parents. Children of older parents are more likely to be in daycare and have greater independence than children of younger parents, whereas children of younger parents are more likely to be at home with parents and other siblings, and encounter more home discipline. A researcher observed the disciplinary habits of 456 families with at least one child, categorizing each as "high" or "low" in terms of disciplinary strictness. The families were also divided into older parents (those 29 years of age or younger) and older parents (30 years old and up). Are the following data consistent with the hypothesis that older parents are not as strict when disciplining their children? Calculate gamma and interpret it's direction and magnitude, and summarize your findings in a few sentences. Level of discipline Parental age 29 years or younger 30 years or…
According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft. In that year, assume some state had 454 complaints of identity theft out of 1660 consumer complaints. Do these data provide enough evidence to show that the state had a higher proportion of identity theft than 23%? Test at the 10% level.

“The US Centers for Disease Control and Prevention said about 72 million Americans—nearly one out of every four of the country’s 304 million residents—are considered obese. Millions more are designated as overweight.” The American trend toward obesity has prompted many physicians to offer weight-loss programs to their patients. [Source: Price, W. T. “Physicians Get into the Weight-Loss Business.” Florida Today, July 7, 2008.] A physician conducted an experimental study to compare the effectiveness of four different weight-loss programs. In the study, 64 obese adults were randomly assigned to the four programs so that each program had 16 adults. The programs lasted for six months. The weights of the subjects were measured before and after the programs, and each subject’s weight loss was computed in pounds. The following table summarizes the results of the study, giving the number of observations and the sample mean and variance of the subjects’ weight loss in each program.…
