In Star Wars Episode 4: A New Hope, Princess Leia says Luke is "a little short to be a storm trooper." To test this we went to New Orleans Comic-Con and took the heights, in inches, of Luke cosplayers and Storm Trooper cosplayers, the data is in the table below.

Lukes	Storm Troopers
x L ¯ = 57	x S ¯ = 60
n L = 10	n S = 15
s L = 3	s S = 2

Use this data, the assumption that the population variances are equal, give a 95% confidence interval for μ S − μ L. Can you conclude that Luke was too short to be a storm trooper?

Group of answer choices

a)None of these

b)3±1.96910+415, The interval does not include 0 so Luke was too short

c)3±1.965.96(910+415), The interval includes 0 so Luke may not have been too short

d)3±2.0695.96(110+115), The interval does not include 0 so Luke was too short

e)3±2.0605.96(110+115), The interval does not include 0 so Luke was too short
