Arivet is to be inserted into a hole. a random sample of parts is selected, and the hole diameter is measured. the sample standard deviation of the hole diameter measurements is millimeters. construct a 99% lower confidence bound for . assume population is approximately normally distributed.

1 1/5

step-by-step explanation:

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
