3. A random sample of 45 students at a high school is collected and their GPA is recorded. The sample mean is computed to be 2.5 with a sample standard deviation of 1.3. i) Construct a 95% confidence interval for the mean GPA of all students at this school. For part (i), do not assume that GPA follows Normal distribution. ii) Construct an interval that is likely to include at least 90% of possible GPA values of students at this...
The ACT is a standardized test that many high school students in the U.S. take in order to apply for college (the other major admissions test is the SAT). Scores on the ACT range from 1 to 36 in one point increments. The dean of a college of business is interested in examining the relationship between ACT scores and GPAs of students in the college. After taking a random sample of 141 students, he performs a regression analysis using Excel...
A university admissions office is studying indicators of high school students’ eventual college performance measure by their grade point averages and class rank. The coefficient of determination between college GPA and high school GPA is found to equal .81. The coefficient of determination between college GPA and high school rank is found to be equal to .64. Based on this information, which of the following is true? Group of answer choices College GPA can be perfectly predicted when using both...
A researcher asks: Are high school students who have tried alcohol more likely to have had sex than students who have never had alcohol? Using the data from the YRBS study, the researcher finds that only 16.7% of high school students who have never tried alcohol have had sex, whereas 56.3% of high school students who have tried alcohol have had sex. Based on these findings, the researcher concludes that drinking alcohol causes high school students to have sex. What...
