Aresearcher wishes to see whether the variances of the process (in seconds) on machine a are different from the variances of process (in seconds) on machines other than machine a. the researcher selects two samples, and the data are below. using a = 0.05, the researcher tests to see if enough evidence exists to support the claim. for machine a, n1 = 16 and = 18. for machines other than machine a, n2 = 18 and = 16. what is the test value f

a

step-by-step explanation:

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 %
