Here the null hypothesis is that the PCB survives against the alternate that the PCB 'does not survive'. The test says that the PCB will survice if it is classified as 'good'; or, it will not survive if it is classifies as 'bad'.

a. The Type II error is the error committed when a PCB which cannot actually survive is classified as 'good'.

b. Therefore P(Type II error) = P(The PCB is classified as 'good' | PCB does not survives) = 0.03.

IrinaK [193]

The professional runner can run 4 1/6 miles in 30 minutes.

Since the professional can run 1 1/4 times as far in 30 minutes, we multiply 3 1/3 by 1 1/4:

(3 1/3)(1 1/4)

Convert each to an improper fraction (multiply the whole number by the denominator and add the numerator):
10/3(5/4) = 50/12 = 25/6 = 4 1/6.
