Answer:
183.4286 lbs
Step-by-step explanation:
given that the population of weights for men attending a local health club is normally distributed with a mean of 178-lbs and a standard deviation of 25-lbs.
Total weight in the lift should not exceed 6420 lbs
No of persons limited = 35
Hence average weight of the person that should be below
If the average exceeds 183.4286 pounds then the elevator would be considered overloaded.
Answer:
Step-by-step explanation:
Garrett achieves a field goal is independent of each kick. Hence X no of kicks is binomial with p = 0.83, and q =0.17
No of trials 3
Hence X can take values as 0 ,1,2,3 and
, r=0,1,2,3
Using the above we obtain prob distribution as
X 0 1 2 3
P(X) 0.0049 0.0720 0.3513 0.5718
P(X>=2) =P(X=2,3,4) =0.9231

2) Z value for company A =
Z value for company B =
From z value probablility is more for company A as
P(Z>-2.22) >P(Z>2.89)
