Answer 1

4. predcited value at X-4: 4.327 (1+1/n+(xo-K)7sxx) std error prediction interval= 1.5719 s for 90 % CI value of t- margin of error E-t"std error lower prediction bound-sample mean-margin of error Upper prediction bound-sample mean+margin of error- 2.132 3.3513 0.976 7.678

from above 90% CI :UPL =7.678 ( please try 7.679 if this comes incorrect)

LPL =0.976
