Adoctor at a local hospital is interested in estimating the birth weight of infants. how large a sample must she select if she desires to be 99% confident that the true mean is within 3 ounces of the sample mean? the standard deviation of the birth weights is known to be 5 ounces.

18

Step-by-step explanation:

Given : Margin of error = 3 ounces

Significance level :

Critical value :

Standard deviation :

The formula to calculate the sample size is given by :-

Hence, the minimum sample size should be 18.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

move it to the other side

step-by-step explanation:
