Use a sample n= 840 , p = 0.25, and a confidence level to construct a confidence interval estimate of the population proportion ,p.

The confidence interval would be (0.221, 0.279).

Step-by-step explanation:

Since we have given that

n = 840

p = 0.25

q = 1 - p =

Let 95% level confidence, z = 1.96

Margin of error is given by :

So, confidence interval would be

Hence, the confidence interval would be (0.221, 0.279).

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
