For a sample size of 140 and a proportion of 0.3 what is the standard deviation of the normal curve that can be used to approximate the binomial probability histogram? round your answer to three decimal places.

0.038

Step-by-step explanation:

We know that for a sample size of N and a proportion of p , the standard deviation of the normal curve that can be used to approximate the binomial probability histogram is given by :-

Given: p= 03.3

N= 140

Then , the standard deviation of the normal curve will be :-

is there any photos or whatever?

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
