Answer:
Since p > alpha, we accept H0, there is no evidence to prove that p1 is greater than p2
Step-by-step explanation:
Set up hypotheses as
(Right tailed t test)
Alpha = 0.05
Sample I II Total
X 117 141 248
N 249 312 561
p 0.4700 0.4519 0.4420
p difference = 0.0181
Std dev =
=0.0427
z statistic = 0.424
p value = 0.33724
Since p > alpha, we accept H0, there is no evidence to prove that p1 is greater than p2
Answer:
pretty hard
Step-by-step explanation:
Answer:
4 units
Step-by-step explanation:
A'B' = 2 × AB
8 = 2×AB
AB = 8/2 = 4
Area = l*w
Area of living room rug = 12(1/2)*10(3/4) = 134.375
Total area - covered areas = areas seen
Total area - couch area - entertainment area = areas seen
134.375 - 12(1/2) - 6 = 115.875
The areas of the rug seen is thus 115.875 square feet. (sq. ft)
