Problem #4 Bumble wants to purchase a tablet only if it can improve efficiency on his reading assignments for classes. To test this, Bumble sampled 45 classmates and asked each of them to read materials first on paper and then on a tablet screen. Performances of the 45 classmates (in words per minute, WPM) are recorded on this Excel file In the file, the scores under "Paper" and "Screen" columns are WPM read on corresponding conditions for each of the 45 classmates. Using the significance level of 0.05 , conduct an appropriate hypothesis test to determine if reading on screen is faster than on paper. 4-1 To help him test this, complete the appropriate H0 and H1 by filling in the blanks: (Separately fill in the parameter, equality, and value by selecting from the dropdown menu.) H0 : H1 : 4-2 What would be the most appropriate critical value (i.e., zcrit or tcrit ) for this test? Separately fill in the name, sign, and value by selecting from the dropdown menu (for example, zcrit=+1.96 ). crit= 4-3 What is the calculated test statistic for this test? *Don't round intermediate calculations. Separately fill in the sign and value by selecting from the dropdown menu. test statistic = 4-4 What is the p-value for this test? Select from the dropdown menu: 4-5 What is the most appropriate conclusion for this hypothesis test? Complete the most appropriate test conclusion by filling in the blanks: Bumble should the hypothesis and conclude about the of reading speed on paper vs. tablet screen that the WPM on screen is the WPM on paper
