Question: Note that n=8. We will define, d = x; - yi. After doing the appropriate calculations, we find that d =-1.375 sd = 9.365.

Note that n=8. We will define, d = x; - yi. After doing the appropriate calculations, we find that d =-1.375 sd = 9.365. we look at the student's t chart for 98% confidence (the 98% is found along the bottom row of the chart) and DOF=8-1=7 (the df=7 is found in the leftmost column) we find that t=2.998. Then D. Sd d- t < a < d + t 505 -1.375 2.998 9.365 8 9.365
