confidence Intervals for group three(it is intentional that group 1 has five intervals)

Group 1 Group 2 Group 3

(61.48, 65.18) ( 60.573, 65.627) ( 62.15, 64.51)

(58.55,65.71) (61.401, 66.479) (60.48, 64.50)

(61.48, 65.18)' ( 61.429, 67.411) ( 60.79, 65.21)

(59.62, 65.614)

(62.24, 64.28)

g)Explain why it does not make sense to count data values that lie in a confidence interval. Think about the random variable that is being used in the problem.

h) Suppose you obtained the heights of ten women and calculated a confidence interval from this information. Without knowing the population mean μ, would you have any way of knowing for certain if your interval actually contained the value of μ? Explain.

Hello I don't understand g but I believed that is impossible because we don't have the information of all the population so we only could hope that our intervals is in 90%. Is that right?
