A researcher was interested in examining a relationship between hours of exercise and concentration level among BYC students. Also, he was interested in examining whether hours of exercise would predict the concentration level. Answer following questions based on the given data.

Exercise (X)                     Concentration level (Y)
0                                                      4
2                                                      1
8                                                      10
6                                                       9
4                                                       6
x̅=4                                               Y=6
SSx = 40                                        SSy=54


Q1: What is the regression line? Y hat = __________
Q2: Compute SS residual.
Q3: Find the standard error of the estimate.

A researcher was interested in the relationship between the reported stress level (variable X) and performance on memory test (variable Y). The data collected on a sample of n = 62  undergraduate students produced the following results: MX = 4, SSx = 30, MY = 6, SSY= 90, and SP = - 15 A. Is there a significant correlation between stress level and memory performance? Assume 2-tailed test, p < .05. For full credit your answer should include: Null and alternative...

Dr. Smith was interested in examining if weekly exercise would produce a change in the stress levels among individuals in the population. In general population of college students, scores on a standardized stress test that are normally distributed with the mean µ = 20 and standard deviation σ = 5. Because it was not feasible to ask everyone in the population to exercise weekly, a sample of n = 16 individuals was selected, and the exercise training program was given...
