Answer is [F and N]
4 is absolute. -4 in absolute form is 4.
I believe the slope is 0 because it they are both horizontal lines? I may be wrong though.
Answer:
(0.059, 0.133)
Step-by-step explanation:
Sample size = n = 250
Number of units which failed the test = x = 24
Proportion of units which failed the test =
= 0.096
Proportion of units which did not fail the test = q = 1 - p = 1 - 0.096 = 0.904
Confidence level = 95%
z-value for the confidence level = z = 1.96
The true proportion of the components that fail to meet the specification would be:

Using the values, we get:

Thus, 95% confidence interval estimate for the true proportion of components, p, that fail to meet the specifications is (0.059, 0.133)
The answer is 10080 you can use a calculator for this
