An ¯x chart with three-sigma limits has parameters as follows: UCL = 86 Center line = 80 LCL = 74 n = 5 (a) (10 pts) Suppose the process quality characteristic being controlled is normally distributed. The true mean is 82 and standard deviation is 6. What is the probability that among three consecutive samples, at least two consecutive samples will be in control?

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
