Answer:
The point estimate for p is 0.86.
Step-by-step explanation:
We are given that in a marketing survey, a random sample of 730 women shoppers revealed that 628 remained loyal to their favorite supermarket during the past year (i.e. did not switch stores).
Let p = <u><em>proportion of all women shoppers who remain loyal to their favorite supermarket</em></u>
Now, the point estimate for the population proportion (p) is represented by ;
Point estimate for p =
=
where, X = Number of women shoppers who remained loyal to their favorite supermarket during the past year = 628
n = sample of women shoppers = 730
So, <u>point estimate for p</u> (
) =
=
= <u>0.86</u>

Answer: Last option.
Step-by-step explanation:
Given the equation:

Follow these steps to solve it:
- Subtract the fractions on the left side of the equation:

- Using the Difference of squares formula (
) we can simplify the denominator of the right side of the equation:

- Multiply both sides of the equation by
and simplify:

- Multiply both sides by
:

- Apply Distributive property and simplify:

- Divide both sides of the equation by -6:

- Factor the equation and solve for "m":

In order to verify it, you must substitute
into the equation and solve it:
