11-1 (modified) suppose that copper prices have dropped so that the break-even level for the mean yield from bacterial leaching rises from 36 lb/ton to 37 lb/ton. after reformulating the engineer's hypotheses from p. 345 (also recall that sigma = 25 and n=100), (a) using the critical value of 40, determine the type i error probability: pr(type i error) =

(b) using the critical value of 40 and assuming mu = 43, findthe type ii error probability:

pr(type ii error) =

is this part of a question or something

idk

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 %
