Liz wants to estimate the percentage of people who rent their home. She surveys 320 individuals and finds that 176 rent their ho
SOVA2 [1]

Answer: 0.065

Step-by-step explanation:

Given : Sample size : n= 320

The sample proportion of people who rent their home : p=\dfrac{176}{320}=0.55

Significance level : \alpha:1-0.98=0.02

Then , Critical value : z_{\alpha/2}=2.33

The formula to find the margin of error : -

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}\\\\\Rightarrow\ E=(2.33)\sqrt{\dfrac{0.55(1-0.55)}{320}}\\\\\Rightarrow\ E=0.064799034281\approx0.065

Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065

1. Solve the equation.
anzhelika [568]
<span>5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x

step1:-   5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5

-x - 20 = 6x + 1

stp 3

-20 = 7x + 1
step 4

-21 = 7x
divide both sides by 7:-

-3 = x

thats the solution   x  = -3
