To determine the smallest sample size needed for a 95% confidence interval with a desired margin of error of 4 grams, I used the formula that relates sample size to margin of error, incorporating the standard deviation of 12 grams and the z-score of 1.96. After calculations, I found that the smallest required sample size is approximately 38 apples.
Javon wants to estimate the mean weight of apples in his orchard. He’ll sample n apples and make a 95% confidence interval for the mean weight, so
z=1.96 He is willing to use a standard deviation of 12 grams as an estimate, and he wants the margin of error to be no more than 4 grams. What is the smallest approximate sample size required to obtain the desired margin of error? Show your work.
To determine the smallest size for achieving a margin of error of 4 G at a 95% confidence level, I used a formula relating sample size, Morgan error, taking into account the Z value for 95% confidence. The smallest sample size required is 38 apples?
use a small sentence to explain, no calculations, just an explanation on how you got the answer, and what the answer is
