Give your answers as decimals, rounded to three decimals.Estimate the minimum sample size needed to achieve the margin of error E = 0.029 for a 95% confidence interval The minimum sample size is (Round up to the nearest integer.)
- Assume that the square footage of a residential house in the US is normally distributed with a mean=1000 and standard deviation=150 square feet. Suppose we select 450 houses from a town and we find that the mean of those houses is 1230 square feet (the standard deviation remains the same). What is the 95% confidence interval for this sample? from 1216 to 1244 from 1250 to 1320 from 1126 to 1294 from 1038 to 1420The heights of pine trees at a local tree farm are known to follow a normal distribution with a standard deviation o = 7 inches. A researcher takes a sample of 99 trees and finds they have a mean height of = 121 inches. Use this to find a 90% confidence interval for the height of all the pine trees at the tree farm. What is the margin of error? *Include 3 decimals places in your final answer* Confidence Interval: ( Margin of Error:Determine the most conservative sample size for 95% confidence interval estimation of the population proportion with maximum error of 0.04.
