In this exercise, we examine the effect of the confidence level on determining the sample size needed. Find the sample size needed to give a margin of error within plus or minus 4 with 99% confidence. With 95% confidence. With 90% confidence. Assume that we use σ=35 as our estimate of the standard deviation in each case. Round your answers up to the nearest integer. 99% n= 95%n= 90% n=
