Answer:
Step-by-step explanation:
This situation can be modeled by a binomial distribution of parameters:
We want to find the probability that at least 90 are in repair.
<u><em>We can approximate this problem to a normal distribution, where:</em></u>
Then we look for
Then we must find the normal standard statistic Z-score
Therefore:
Looking in the standard normal table we obtain:
Answer:
(7, 64.33)
Step-by-step explanation:
For a woman suspect whose shoe size was found at the crime scene, the equation which can be used to predict the estimated height is given as:
(a)Let x=7
Then: y =1.19(7)+56=64.33
An ordered pair that is a solution to the function is (7, 64.33)
(b) The estimated height of a woman who is of shoe size 7 is 64,33 inches.
