1. The famous research team of Robert Cray and the Crayuns believes that the amount of rainfall is significantly linearly related to corn yield on average. Results of a simple regression on the effects of rainfall (x) on corn yield (y) showed the following sample regression line for 30 observations:
yi = 2.5 + 3.2x1; with sb1 = .11 SST = 1000, SSE = 300
Test this belief at the 10% level of significance.
a) State hypotheses
b) Calculate test statistic
c) Calculate the critical value
d) State conclusion
e) What is the variance in corn yield for this sample?

The Admissions officer for the graduate programs at Michigan State University (MSU) believes that the average score on the GRE exam at his university is significantly higher than the national average of 1300. Assume that the population standard deviation is 125 and a random sample of 25 scores had an average of 1375. State the appropriate null and alternative hypotheses Calculate the value of the test statistic and set up the rejection region. What is your conclusion? Calculate the p-value...
5. L. Wallace, the president of a major public university, believes students’ grade-point-averages [GPAs] decline when students transition from high school to college, on average. To test President Wallace’s belief, you selected a random sample of 41 students enrolled in BMGT 230 this semester and conducted a test to compare each student’s high school GPA [HS_GPA] to their current college GPA [COLL_GPA]. Use the MS Excel output below to answer/complete Parts a through d: t-Test: Paired Two Sample for Means...
A new kind of typhoid shot is being developed by a medical research team. The old typhoid shot was known to protect the population for a mean time of 36 months, with a standard deviation of 3 months. To test the time variability of the new shot, a random sample of 17 people were given the new shot. Regular blood tests showed that the sample standard deviation of protection times was 1.5 months. Using a 0.05 level of significance, test...
A real estate research firm has developed a regression model relating list price (Y in 1,000) with two independent variables.
