Two machines are used for filling glass bottles with a soft-drink beverage. the filling processes have known standard deviations liter and liter, respectively. a random sample of bottles from machine 1 and bottles from machine 2 results in average net contents of liters and liters. (a) test the hypothesis that both machines fill to the same net contents, using what are your conclusions? (b) find the p-value for this test. (c) construct a 95% confidence interval on the difference in mean fill volume.

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 %

answer: b f g .

step-by-step explanation:

add 8+12 to get a simplified answer of 12r-20
