Answer:
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
Step-by-step explanation:
The scenario presented can be modeled by a binomial model;
The probability of success is, p = 0.65
There are n = 80 independent trials
Let X denote the number of drivers that wear a seat belt, then we are to find the probability that X is greater than 42;
Pr(X > 42)
In this case we can use the normal approximation to the binomial model;
mu = n*p = 80(0.65) = 52
sigma^2 = n*p*(1-p) = 18.2
Pr(X >42) = Pr( Z > -2.344)
= Pr( Z< 2.344) = 0.9905
For the answer to the question above asking <span>Melissa is helping her dad build a walkway in their backyard. The walkway will be 545454 feet long and 1.51.51, point, 5 feet wide. The local hardware store sells tiles which are 1.51.51, point, 5 by 1.51.51, point, 5 feet and come in boxes of 121212.</span>
54 dived by 1.5 is 36.
36 dived by 12 is 3.
You need 3 boxes.
