Jump to level 1 Use Sheet 1 of the Excel file to answer the following questions. A school administrator believes that the mean class GPAs for a given course are higher than the preferred mean of 2.75 at a significance level of 0.05, and checks a randomly chosen sample of 50 classes. Create a histogram, and calculate x, the t-statistic, and the p-value. From the histogram, can normality be assumed? Pick Ex = 2.75 p = Since the p-value is Pick than the significance level 0.05, the null hypothesis Pick Pick evidence exists that the mean GPA is greater than 2.75. 3.09 2.73 2.58 2.68 Chart Title 2.84 2.68 2.64 2.62 25 2.35 20 2.72 2.63 15 2.77 2.72 10 3.03 2.71 2.96 OUT 2.74 3.01 [2.34, 2.52] (2.52, 2.70] (2.70, 2.88] (2.88, 3.06] (3.06, 3.24] 2.88 2.68 2.83 3.02 2.83 2.71 2.67 2.79 2.65 2.56 2.78 2.89 2.40 2.38 2.41 2.83 2.86 3.01 2.80 2.84 2.95 2.75 2.93 2.48 2.34 2.97 2.85 2.74 2.84 3.10 2.62 2.77
