Where SAT is the student’s SAT score, Athlete is a dummy variable for if they were a college athlete, High School Rank is their ranking in their high school (1 being the highest), Female being a dummy variable for if they are female, and Total Cred Credit Hours being the total credit hours taken in college.   GPA measures the student’s GPA in college.

Answer the following questions and upload ALL of your work in either a word document, or picture.  

a) Determine the test statistic for the Athlete Variable

b) Interpret the coefficient on the Total Credit Hours variable

c) Which of the following variables can you reject the null that they have no correlation with the dependent variable of GPA, an WHY?

d) What is the change in a student's predicted GPA from scoring 200 points higher on their SAT score?

Let the random variable X represent a student’s score on an IQ test. Suppose that student IQ scores are Normally distributed with a mean of 100 and a standard deviation of 15. Part A.Any student who scores at least 130 on an IQ test would be considered gifted. If a student has scored 130 on an IQ test, what percentile does this score represent? Part B.In a class of 50 students, how many would you expect to score at least...

For a specific year, the average score on the SAT Math test was 525. The variable is normally distributed, and the population standard deviation is 105. A superintendent wishes to see if her students scored significantly higher than the national average on the test. She randomly selected 45 student scores and the mean for this sample was 545. At α = 0.05 , is there enough evidence to support the claim? μ = _________ σ = _________ n = _________...

13.28 800 on the SAT. It is possible to score higher than 800 on the SAT, but scores above 800 are reported as 800. (That is, a student can get a reported score of 800 without a perfect paper.) In 2014, the scores of college-bound senior men on the SAT Math test followed a Normal distribution with mean 530 and standard deviation 123. What percentage of scores were above 800 (and so reported as 800)?

The statistics department is interested in the different factors that might influence a student’s score on the final exam. They identify three factors to test: the student’s midterm exam score, the number of hours the student reports having studied for the final exam, and the average number of drinks of alcohol the student reports having on a night out. They collect data on all of these factors and want to estimate the following model: FinalExamScore=β0+β1 MidtermExamScore +β2HourStudied +β3AverageAlcohol +ε Variable...

(a) Find the sample mean and sample standard deviation for this sample. (b) Find a 90% confidence interval for the mean score of all the students. Interpret the result. (c) Test, at significance level 10%, if the average score is lower than 70.
