population sd 24
sample mean 125
sample size 36
confidence level 0.99
standard error of mean 4
z 2.575829
interval half width 10.30332
lower 114.6967
upper 135.3033

formulas

population sd 24
sample mean 125
sample size 36
confidence level 0.99
standard error of mean =B2/SQRT(B4)
z =NORMSINV(B5+(1-B5)/2)
interval half width =B8*B7
