Lower confidence limit? Upper confidence limit best point estimate margin of error

Prof. K. wants to estimate the average cost of a dozen eggs last week. To do this they gathered a sample of the costs of a dozen store brand eggs from 25 stores, The sample yielded a mean of $1.68 and a standard deviation of 0.25. Find the 95% confidence interval for the mean, interpret the confidence interval, and decide if the mean cost of a dozen eggs is $1.50. Which ti84 function is required to find the confidence interval? Z-Interval What are the following values? n= 25 D= = 0.25 S= 1.68 Confidence level = 0.95 Lower confidence limit = none of these is correct Upper confidence limit = [ Select ] Best point estimate [Select ] Margin of Error = [Select ]
