<PRE><B>Question 835614</B>
A 95% confidence interval for the mean weight when 40 pumpkins are sampled gives 4.71kg  5.93kg .
i) What is the mean weight of the 40 pumpkins?
mean = (5.93+4.71)/2 = 5.32
---------------------------------------
ii) What is the margin of error in this confidence interval?
ME = (5.93-4.71)/2 = 0.61
