Question two asks, can a student keep up their grade performance at the next level (Mirabella, 2011)? Is a strong GPA at the Bachelors level a good predictor of a strong GPA at the Masters level (Mirabella, 2011). Are GPAs naturally going to decline since graduate school is tougher (Mirabella, 2011)? Will GPAs automatically be higher in graduate school because of the 3.00 requirement to graduate (Mirabella, 2011)? The treatment of a C as subpar, instead of average (Mirabella, 2011). Using the sample of 200 students, conduct a hypothesis test for paired samples (Mirabella, 2011). Test if there is a difference in the mean GPA from the Bachelors to the Master's programs (Mirabella, 2011). Use a .05 significance level (Mirabella, 2011). The…show more content…
Once the differences are all accounted, then add up the total differences and divide by the sample size two-hundred (Mirabella, 2011). The total from the total differences divided by the sample size will be the difference sample mean. Use the T-test to find the test statistic value (Mirabella, 2011). T = Xd(with a line over the top) – Hypothesized value/standard deviation/square root of n(sample size) (Mirabella, 2011). T = 1.9720 (Mirabella, 2011). Obtain the P-value using a TI-83/84 Calculator (McGraw, 2017). Go to DISTR menu which you can access by pressing [2nd] [VARS] (McGraw, 2017). Choose tcdf (#6 on the TI84) (McGraw, 2017). Tcdf (1.97, 99 (T-value)) (McGraw, 2017). P-value = 0.0000 (area) (McGraw, 2017). P-value = 0.0000 Alpha = 0.05 (Mirabella, 2011). P-value 0.0000 < Alpha 0.05 (Mirabella, 2011). If the P-value is less than (alpha) 0.05, then reject the null hypothesis (Mirabella, 2011). If the P-value is greater than (alpha) 0.05, the fail to reject the null hypothesis (Mirabella, 2011). P-value 0.0000 < Alpha 0.05 (Mirabella, 2011). Since the P-value is less than the level of significance rejects the null hypothesis (Mirabella, 2011). In conclusion, reject the null hypothesis and conclude a difference in the mean GPA’s of the students from the Bachelors to the Master’s programs (Mirabella, 2011). Question three asks, given the reasons why people get their Masters, men are more likely to declare a major
