Calculate the Lower Limit????????

I need help figuring out how to find the answers for the last 4 questions based on the table above.

Explanation / Answer

MOE = z * Std error

std error = std devn/ sqrt (n)

z is the critical value at alpha = 0.05 (check normal distribution table for the value, it is 1.96)

Upper Limit = Xbar + MOE

Lower Limit = Xbar - MOE
