A machine produces metal plates used in an automobile suspension system. A random sample of 20 plates is selected, and the thickness is measured. The resulting data (in millimeters) are as follows: 14.86 14.43 14.05 14.00 13.87 14.65
14.31 14.24 14.49 14.15 14.13 14.80
14.34 14.11 13.90 13.75 13.76 14.47
13.84 14.51
(a) Use a Normal Probability Plot to check the assumption of normality for plate thickness. Discuss the plot and your conclusions.
(b) Use a 95% Confidence Interval to determine if it is it believable that the mean plate thickness if 14.15mm?
(c) Is it believable the standard deviation of plate thickness is less than 0.35 mm? Construct the appropriate 99% confidence interval.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

step-by-step explanation:

sry but any answer choices

its   c, f, a

step-by-step explanation:

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.

you!
