Answer:
30 men
Step-by-step explanation:
In order to be sure that the sample mean does differ from the population mean by more than 0.90, the sample size (n) that should be used is given by:
Where 'Z' , for a 95% probability is 1.960, 's' is the standard deviation of 2.5 inches:
Rounding up to the nearest whole number, the sample size should be at least 30 men.
A function can be represented on a table and on a graph.
The models of the linear relationship between f(x) and x are:
The given parameters are:
So, the function that models the linear relationship is:
Substitute known values
Evaluate all products
Rewrite as:
By comparing the above function to the list of options, we have the true options to be:
