A magazine collected the ratings for food, decor, service and the cost per person for a sample of 96 restaurants. They combined the ratings to create a summated rating and used that to predict the cost of a restaurant meal. The data are modeledby Y; = - 30.871 + 0.9349X;, where X; is the summated ratings and Y; is meal cost. For these data, Syx = 8.575, X= 61.02, and h; = 0.027122 when X = 52.

In a sample of 47 men, 36 said that they had less leisure time today than they had 10 years ago. In a sample of 47 women, 30 women said that they had less leisure time today than they had 10 years ago. At a = 0.05, is there a difference in the proportions? Use p, for the proportion of men with less leisure time.
A study wants to investigate whether eating oat bran lowers the serum cholesterol levels. Fourteen individuals were randomly selected and their serum cholesterol was measured. Then, they were assigned to an oat bran diet for two weeks, and their serum cholesterol was measured at the end of that period. The differences on the serum cholesterol levels before and after the diet can be summarized below: 14 14 D; = 5.08, > (D; – D)² = 2.142, D; = Cholesterol; before - Cholesterol; after, i=1 i=1 where D; is the difference between the cholesterol level before and after the diet. Do these results provide evidence that the diet lowers the cholesterol levels? Use a 0.05 level of significance. Assume that cholesterol levels are normally distributed. Hint: S3 = 2 D.-D)? 14-1
An article in the Archives of Internal Medicine reported that in a sample of 224 men, 73 had elevated total cholesterol levels (more than 200 milligrams per deciliter).

Do women and men differ in how they perceive their life expectancy? A researcher asked a sample of men and women to indicate their life expectancy. This was compared with values from actuarial tables, and the relative percent difference was computed; perceived life expectancy minus life expectancy from actuarial tables was divided by life expectancy from actuarial tables and converted to a percent. The relative percent differences for all men and women over the age of 7070 in the sample are given. Men −28−28 −23−23 −20−20 −19−19 −14−14 −13−13 Women −20−20 −19−19 −15−15 −12−12 −10−10 −8−8 −5−5 The given data shows output for the two‑sample ?t test using Option 1. This output is from CrunchIt! software, which does Option 1 without rounding or truncating the degrees of freedom. Do men and women over 70 years old differ in their perceptions of life expectancy?

Brandon works as a statistician for the Toronto Blue Jays, and wants to analyze the relationship between a player's age and how many strikeouts they accumulate in a season. He takes a sample of 5 Blue Jays players with age between 25 and 34 and finds there is a linear relationship between their ages and the number of strikeouts they had in the 2015 season. Here are the numerical summaries for age and the number of strikeouts: r = 0.6, age = 25.3, Sage = 3.2, strikeout = 105.7, S strikeout = 7.48 a) What is the value of b₁, the estimated slope? (Round your answer to 3 decimal places, if needed.) Answer: b) What is the value of bo, the estimated intercept? (Round your answer to 3 decimal places, if needed.) Answer: c) What is the percent of variation in the number of strikeouts that is explained by age, using linear regression? (Round your answer to 2 decimal places, if needed.) Answer: % d) Can we use this linear regression to predict the number of strikeouts for a player age at 37? No,…

The accompanying table shows the height and weight of five football players in training camp. The body mass index (BMI) is used to assess the relative amount of fat in a person's body. If w is weight in pounds and h is height in inches, then BMI = 703wh. Some physicians consider your body fat abnormal if your BMI satisfies BMI-23>3. Which of the five players does not have abnormal body fat? does not have abnormal body fat. Player D Player B Player C Player E Player A ..
