To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades: 4.0 in a 5 credit Math course 2.5 in a 3 credit Music course 2.7 in a 5 credit Chemistry course 3.3 in a 6 credit Journalism course What is the student's GPA for that term? Round to two decimal places Student's GPA =
Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours). 2.4 t (to 3 decimals) 2.8 Select your answer - 2.2 Ho : μ Select your answer - 2 Ha - Select your answer - ✪ 2 b.

A magazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. Among the 1500 respondents, 13% chose chocolate pie, and the margin of error was given as t4 percentage points. Describe what is meant by the statement that "the margin of error was given as ±4 percentage points." Choose the correct answer below. O A. The statement indicates that the interval 13% + 4% is likely to contain the true population percentage of people that prefer chocolate pie. O B. The statement indicates that the study is 100% - 4% = 96% confident that the true population percentage of people that prefer chocolate pie is 13%. C. The statement indicates that the study is only 4% confident that the true population percentage of people that prefer chocolate pie is exactly 13%. O D. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 13% +4%.

Harper collected data on students who make appointments to see their advisor to see how many failed to show up. The student records were divided into two groups: male (group 1) and female (group 2). A 93% confidnece interval for pi – P2 was found to be as follows: (0.03, 0.09) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.
