The formula for finding the area of the circle works because they made it especially for it. I don’t really know how else to describe it, it simply just works.
A)During 0 week old factory have 40 more products than the new factory.
B)I am so sorry that I forgot how to find the. Rate of growth :)
C)at week 4 the new factory exceed the old factory because new factory produce 337 products and old factory only produce 336.74.
Hope it will help:)
Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
