22).i am using minitab to solve the problem.
steps :-
copy the data in minitab and name the column x stat basic statistic 1 sample t select one or more samples each in a column in the blank box below select Xoptions in confidence level type 90 in alternative hypothesis select mean hypothesized cake okok.
the needed minitab output be:-
90% CI for μ |
(13.77, 22.56) |
23).given data are:-
the 95% confidence interval be:-
the lower limit is = 0.525
24).sample size (n) = 21
df = (n-1) = (21-1) = 20
according to the problem:-
[ in any blank cell of excel type =T.INV(0.975,20) ]
the value of A is = 2.086
