問題詳情

10. Consider tbe infinite population described by the probability distribution show here.

Assume a rindom sumple of n = 80 measurenents is selected from the population, find the sampling distrioution of thesample mean 

 and calculate P (0.905＜

＜1.095)
(A) 

= 1. P(0.905 ＜

 ＜ 1.905) =0,7330
(B)

= 1, P(0.905＜

 ＜1.905) = 0.6578
(C) 

= 1.2. P(0.905 ＜

＜1.905)= 0.7920
(D)

= 1.2, P(0.905＜

＜ 1.905)=0.9505
