Answer 1

sample mean sample size sample std deviation 26.000 16.00 3.200 nE standard errror of meanx-S/Vn- 0.8000 for 95% CI; and 15 degree of freedom, value of margin of error E-t std error lower confidence bound-sample mean-margin of error- Upper confidence bound-sample mean+margin of error- 2.1310 1.705 24.30 27.70 SxsV(1+1/n)- standard errror of mean- for 95% CI; and 15 degree of freedom, value of margin of error E-t std error lower prediction bound-sample mean-margin of error- Upper prediction bound-sample mean +margin of error- 3.298 2.1310 7.03 18.97 33.03

a)

from above 95% CI =24.30 ; 27.70

b)

95% PI =18.97 ; 33.03
