What statistical test would you use in each situation? Your options are Pearson Correlation Coefficient, Partial Correlation, Regression, t-test, or ANOVA. Situation You want to know whether amount of time spent exercising (in number of minutes) predicts amount of weight lost (in pounds). Statistic You want to compare average exam percentage between two groups: males and females. You want to know whether outside temperature (in degrees Fahrenheit) is related to happiness (on a scale from 1-50). You want to know whether amount of hours spent studying is significantly different between four groups: Freshmen, Sophomores, Juniors, and Seniors. You want to know whether outside temperature (in degrees Fahrenheit) is related to happiness (on a scale from 1-50), controlling for number of hours of sunlight.

Statistics teacher realize that his studentS keep using cell phones during the class. Then he did some research and found out that people use cell phones for 7.2 hours per day on average in turkey, and usage time variability around that average is 2.0449 Then he decides to givean assignment of reading books as an alternative of cell phone usage in exchange of 50 extra credit to their statistics exam. After the exam, He collected the data of cell phone usage time from his 127 students and calculated that average cell phone usage time drops to 6.8 hours per day. Under the assumption that probability of uncontrolled factors leading you the wrong statistical decision is five percent, conduct the statistical analysis to decide whether decrease in the cell phone usage time is real or it happens just because of the random chance and interpret the results.

psychologist is studying the self image of smokers, as measured by the self-image (SI) score from a personality inventory. She would like to examine the mean SI score, u, for the population of all smokers. Previously published studies have indicated that the mean SI score for the population of all smokers is 80 and that the standard deviation is 12, but the psychologist has good reason to believe that the value for the mean has changed. She plans to perform a statistical test. She takes a random sample of SI scores for smokers and computes the sample mean to be 72 Based on this information, complete the parts below.
