In your sample, there are two groups of people: those who have a high school degree and those who have a bachelor's degree or higher. The following table shows the sample statistics of the two groups. You hypothesize that in general those who have a bachelor's degree or higher should earn more than those who have a high school degree. The estimated standard error is $360.

16: How do you solve?
The Cadet is a popular model of sport utility vehicle, known for its relatively high resale value. For a random sample of 33 Cadets, each bought "new" two years ago and each sold "used" within the past month, the least-squares regression equation relating the two variables mileage (denoted by x) and used selling price (denoted by y, in dollars) was y = 39.52 – 0.56x . The standard error of the slope of this least-squares regression line was approximately 0.43. Based on this information, test for a significant linear relationship between the two variables by doing a hypothesis test regarding the population slope B,. (Assume that the variable y follows a normal distribution for each value of x and that the other regression assumptions are satisfied.) Use the 0.10 level of significance, and perform a two-tailed test. Then fill in the table below. (If necessary, consult a list of formulas.)

how do i put part c into the computer? Takeout Food A magazine article reported that 15% of adults buy takeout food every day. A fast-food restaurant owner surveyed 220 customers and found that 42 said that they purchased takeout food every day. At =α0.05, is there evidence to believe the article's claim?
