No u didn’t, the line is wrong. from the point -1 it should intercept (-2,-4) and (2,2)
The answer to the first question is b
I don’t know the answer to the second one sorry
The sample was 10 numbers.
4 of the numbers are less than 301.
So 4 out of 10 would be defective.
4/10 = 0.4 x 100 = 40%
He would expect 40% to be defective.
