Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

Suppose x has a distribution with u = 12 and o = 7.
(a) If a random sample of size n = 45 is drawn, find uy, ox and P(12 < x < 14). (Round , to two decimal places and the probability to four decimal places.)
阪=
Ox =
P(12 < x< 14) =
(b) If a random sample of size n = 60 is drawn, find ux, o y and P(12 <x< 14). (Round o z to two decimal places and the probability to four decimal places.)
阪=
ox =
P(12 < xs 14) =
(c) Why should you expect the probability of part (b) to be higher than that of part (a)? (Hint: Consider the standard deviations in parts (a) and (b).)
The standard deviation of part (b) is ---Select--
part (a) because of the
-Select--- v sample size. Therefore, the distribution about ug is
--Select--
