SAT scores in one state is normally distributed with a mean of 1526 and a standard deviation of 112. Suppose we randomly pick 46 SAT scores from that state. a) Find the probability that one of the scores in the sample is less than 1529. P(X<1529)P(X<1529) =  b) Find the probability that the average of the scores for the sample of 46 scores is less than 1529. P(¯¯¯X<1529)P(X¯<1529) =

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.
