SOLUTION

The point estimate denoted with the symbol p is calculated with this formula.

[tex]p=\frac{successes}{total\text{ sample}}[/tex]

From the question:

successes = 45 (the reason is that we were told that 45 had that characteristic, in other words 45 were successful)

Total sample = 100 ( a sample of 100 people)
