Answer:

Step-by-step explanation:
Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation

If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:

If the modulus function is positive then:

If the modulus function is negative then:

multiply through by -1

combining the resulting inequalities, the estimate of the possible range of heights will be

Answer:
the test I will perform is d. Two-sided t-test
Step-by-step explanation:
When we are to compare between different data, critical regions occur on both sides of the mean of a normal distribution,they are as a result of two-tailed or two-sided tests.
In such tests, consideration has to be given to values on both sides of the mean.
for this question, it is expected to compare weather it is true that first born have different intelligent or not, weather to accept a null hypothesis or reject.
For example, if it is required to show that the percentage of metal, p, in a
particular alloy is x%, then a two-tailed test is used, since the null hypothesis is incorrect if the percentage of metal is either less than x or more than x.
