i need help in this question

Suppose you constructed 90% confidence intervals for a using 20 sets of real data.

Remember that for the two printouts used in this lab--z confidence intervals and t confidence intervals--MINITAB issimulatingwhat confidence intervals do to illustrate the accuracy of the estimating.The reason we construct confidence intervals for is to estimate ; therefore when working with real data (NOT a simulation like in this lab printouts) to construct confidence intervals for , 's value is unknown.

.Could you tell which of these 20 intervals did and which intervals did not contain ?

Yes or NO

ii.Why or why not?
