Serga [27]

Answer;

4 or more tubes or paint.

Step-by-step explanation:

54- 8.50x > 20

-54               -54

 

-8.50x > -34

larisa86 [58]

Answer:  0.0432

Step-by-step explanation:

Formula of Margin of Error :-

E=z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}

Given : Sample size : n= 400

The proportion of individuals use public transportation.=\dfrac{65}{330}\approx0.20

Level of confidence = 0.95

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Substitute the values in the given formula , we get

E=(1.96)\sqrt{\dfrac{0.2(1-0.2)}{330}}\\\\\Rightarrow\ E=0.043157779593\approx0.0432

Hence, the margin of error for the confidence interval for the population proportion with a 95% confidence level. = 0.0432
