As part of an insurance company’s training program, participants learn how to conduct an analysis of clients’ insurability. The goal is to have participants achieve a time in the range of 30 to 47 minutes. Test results for three participants were: Armand, a mean of 37.0 minutes and a standard deviation of 3.0 minutes; Jerry, a mean of 38.0 minutes and a standard deviation of 2.0 minutes; and Melissa, a mean of 38.5 minutes and a standard deviation of 2.9 minutes. a.Which of the participants would you judge to be capable? (Do not round intermediate calculations. Round your answers to 2 decimal places.)

Participants :

Armand: Cpk Cp Capable ? No/Yes

Jerry: Cpk Capable ? Yes/No

Melissa Cp No/Yes

b.Can the value of the Cpk exceed the value of Cp for a given participant?

yes or no

1) cpk < 1.33, therefore it is not capable

b) cpk = 1.33, therefore it is capable

c) cpk < 1.33, therefore it is not capable

2) Cpk can never be greater than the Cp, but can be equal to it

Step-by-step explanation:

Upper limit (USL) = 47 minutes and Lower limit (LSL) = 30 minutes

1)

a) mean (μ) = 37 minutes, standard deviation (σ) = 3 minutes

cpk < 1.33, therefore it is not capable

b) mean (μ) = 38 minutes, standard deviation (σ) = 2 minutes

cpk = 1.33, therefore it is capable

c) a) mean (μ) = 38.5 minutes, standard deviation (σ) = 2.9 minutes

cpk < 1.33, therefore it is not capable

2) Cpk can never be greater than the Cp, but can be equal to it

Using the pythagoras theorem 
r^2 = 12^2 + (18-r)^2
r^2 = 144 + 324 - 36r + r^2
36r = 144 + 324 = 468
r =  468 / 36 = 13 cm Answer

sin 1/2 < AOB = 12 /13
1/2 < AOB =  67.38
< AOB = 134.8 Answer

Area of major sector OAPB

ARea of the circle = pi r^2 = 144pi

so area of mafor sector OAPB =  (225/2 / 360) * 144pi =  90.08 pi  or
283 cm^2 to nearest whole number
