- In a sample of 12 randomly selected high school seniors, the mean score on a standardized test was 1200 and the standard deviation was 160.5. Further research suggests that the population mean score on this test for high school seniors is 1016. Does the t-value for the original sample fall between −t0.90 and t0.90? Assume that the population of test scores for high school seniors is normally distributed.arrow_forwardThe following data are from a random sample of 10 students who participated in a study undertaken to investigate the effect of sleep time (measured in average number of hours of sleep per night) on GPA (grade point average, measured on a 4-point scale).

The researchers suspected that the mean depression score for male teens is higher than for female teens, and wanted to check whether data would support this hypothesis. If μ1 and μ2 represent the mean depression score for male teens and female teens respectively, which of the following is an appropriate pair of hypotheses in this case? Check all that apply.arrow_forward

The lower and upper specification limits under which the ball bearings can operate are 0.73 inch and 0.77 inch, respectively.
