We have weighed 8 randomly selected cinnamon buns from a pastry shop. The weights were according to
following (unit grams)
111, 85, 109, 124, 113, 127, 88, 101
(a) Calculate a 95% confidence interval for the average weight for all
cinnamon buns at this pastry shop. Specify the conditions to be met.
(b) Enter the margin of error for the interval from the (a) task. We plan to do that
about the investigation at another patisserie. What can we do to make one
less margin of error? Motivate the answer
