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.

Find the value of y when x = 10, if y = 35 when x = 7.

olga55 [171]

Set up a proportion:

y = 35 when x = 7

y = ? when x = 10

To get x from 7 to 10, you have to multiply by $\frac{10}{7}$ . Therefore, you do the same to 35, and you get:

$35 \times \frac{10}{7} = 50$

And your answer is 50 :)
