Step-by-step explanation:
Answer:
There is significant difference between the proportions
Step-by-step explanation:
Given that the two statistics classes were asked if A Christmas Story is the best holiday movie.
Class I II Total
n 40 50 90
x 30 45 75
p=x/n 0.75 0.90 0.8333
H0: p1 =p2
H0: p1 ≠p2
(Two tailed test at 5% level)
p difference = -0.15
STd error for difference =
Z statistic = p difference/std error
=-4.0246
p <0.00001
Since p <0.05 we reject H0. There is significant difference between the proportions
At 0.01 level also p is less than alpha So same conclusion
