You have collected a sample of size 100 data points and compute a 90% confidence interval for the mean amount of bread gotten by workers in boulder county. the confidence interval you obtained is [5, 15], where the units are loaves/day. you want to check this result using a larger sample, so you collect a new sample of size 900. the mean of your new, larger sample is 1 loaf/day higher than the smaller sample, but the standard deviation is the same. using the sample of size 900, what is the 90% confidence interval for mean amount of bread gotten by workers in boulder county?
