Hi 
Population: normally distributed, with a <u>standard deviation of 20</u> and a mean of 100 points
Sample:  n = 95 
probability that the sample mean of IQ scores will not differ from the 
population mean by more than 2 points
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
P ( 98, 102, 100,20) =  .0797
Wish You the Best in your Studies.
