(a) Let p represent the proportion of all supermarket shoppers who always stock up on an item when they find a real bargain. Find a point estimate for p. (Enter a number. Round your answer to four decimal places.)

0.2762

Step-by-step explanation:

The point estimate is the best guess of the true parameter. It is an estimate of a population parameter and it is a single value of statistics.

The sample proportion is the point estimate of the population proportion p

Given that

The sample mean = 274; &

The sample size = 992

Then,

The point estimate

p = 0.2762

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
