Swype is an input technique for touch screen devices that allows users to input a word by sliding a finger from letter to letter. The user’s finger is only removed from the keyboard between words. The following table shows the typing speeds of 10 individuals who were measured typing using both methods. These data can also be found in the Excel file Swype.xlsx.
a. Perform a hypothesis test using α = 0.05 to determine if the average typing speed using these two input ­methods is different.
b. Approximate the p value using Table 5 in Appendix A and interpret the result.
c. Verify your results using Excel’s Data Analysis. Mac users can rely on PHStat for this procedure.
d. Identify the p value using Excel and interpret the result.
e. What assumptions need to be made in order to perform this procedure?
