Fatimah wants to build a one-sample z interval to

estimate the proportion of students at her school who ate

breakfast every day last week with 90% confidence. She

takes a random sample of 75 students and finds that 20

ate breakfast every day last week.

What critical value z* should Fatimah use to construct

this confidence interval?

A) z* = 1.282

B) z* = 1.645

C) z* = 1.96

D) z* = 2.576

answer: check all that apply, where the options?

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
