Answer:
And if we solve for a we got
The 95th percentile of the hip breadth of adult men is 16.2 inches.
Step-by-step explanation:
Let X the random variable that represent the hips breadths of a population, and for this case we know the distribution for X is given by:
Where and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
We can find a quantile in the normal standard distribution who accumulates 0.95 of the area on the left and 0.05 of the area on the right it's z=1.64
Using this value we can set up the following equation:
And we have:
And if we solve for a we got
The 95th percentile of the hip breadth of adult men is 16.2 inches.
The population of the group in 2019 is 2,134,000 people
Let P represent the population in thousands of people in the year t after 2011
Given the equation:
a) The population of the group in 2019, that is t = 8(2019 - 2011):
b) The population of the group in 2029, that is t = 18(2029 - 2011):
The population of the group in 2019 is 2,134,000 people
