Answer:
Step-by-step explanation:
Given that X, the hip width of men is N(14.2, 0.9)
i.e. we have is N(0,1)
Seat width an airline uses = 16.7 inches.
a) the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.7 in
b) Here sample size = 126
Each person is independent of the other
the probability that these men have a mean hip breadth greater than 16.7
= <0.00001
c) part a is important since even a single person not fitting will cause embarassment and leads to customer dissatisfaction.
Answer:
1)(0.75,55)
2)(1.5,28)
3)(2,0)
(2.25,-17)
(3,-80)
(4,-192)
Step-by-step explanation:
1) substitute "t" values in table into the equation:
64-16(0.75)^2=
55
64-16(1.5)^2=
28
64-16(2)^2=
0
64-16(2.25)^2=
-17(ball already reached ground and went underground)
64-16(3)^2=
-80
64-16(4)^2=
-192
