In a prior sample of corn, farmer Carl finds that 16% of the sample has worms but the margin of error for his population estimate was too large. He wants an estimate that is in error by no more than 1.5 percentage points at the 90% confidence level.
(a) What is the minimum sample size required to obtain this type of accuracy? Use his prior sample proportion in your calculation.
The minimum sample size is ____ ears of corn.
(b) What is the minimum sample size required to obtain this type of
accuracy when you assume no prior knowledge of the sample
proportion?
The minimum sample size is ___ ears of corn.

Fair Coin? In a series of 100 tosses of a token, the proportion of heads was found to be 0.58. However, the margin of error for the estimate on the proportion of heads in all tosses was too big. Suppose you want an estimate that is in error by no more than 0.05 at the 95% confidence level. (a) What is the minimum number of tosses required to obtain this type of accuracy? Use the prior sample proportion in your...
