A machine cuts plastic into sheets that are 45 teet (540 inches) long Assume that the population of lengths is normaly distrbuted Complete parts (a) and (b) (a ne company wants to est ate t e me anle gth t e machine scut n the pla wit n 1 S nch et mine the mm rum sa e szere u red co struct a 95% re e le at or ne population, mean. As u e re p lati tandard te ation is 0 25 inch Round up to the nearest whole number as needed ) b) Repeat part (a) using an error tolerance of 0 0625 inch Round up to the nearest whole number as needed) Which arror tolerance requres a larger sample size? Explan O A. The tolerance E-00625 inch requires a larger sample size As error size increases, a larger sampke must be taken to ensure the desired ac O B The tolerance E O C. The tolerance E-0 125 inch requires a larger sample size As error sze increases, a larger sample must be taken to ensure the desired accuracy 0 0625 inch requires a larger sample size. As error size decreases, a larger sample must be taken to ensure the desired accuracy D. The tolerance E 125 itch tequares a lar er sample size As error sue decreases a larger sample must be taken t o ensure the desired accuracy
