Question 1101850
This is a t-distribution with mean 936 gm and sd= 25/sqrt(34)=4.29(which is the standard error of the mean)
t=(928-936)/4.29=-1.86
t=(944-936)/4.29=+1.86
probability is 0.9284
-----------------
less than 932 is t< (932-936)/4.29<-0.93
probability is 0.1795
-----------------
within 4 grams is between -0.93 and +0.93, and that is 1-2(0.1795)=0.6410
