Small boxes of NutraFlakes cereal are labeled "net weight 10 ounces." Each hour, a random sample of 6 boxes is weighed to check process control. Five hours of observations yielded the following sample information. Construct a 3-sigma R chart. What does the chart tell you?

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
