Answer: 1.467

Step-by-step explanation:

Formula of Margin of Error for (n<30):-

E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 22

Level of confidence = 0.90

Significance level : \alpha=1-0.90=0.10

By using the t-distribution table ,

Critical value : t_{n-1, \alpha/2}=t_{21,0.05}= 1.720743

Standard deviation: \sigma=4

Then, we have

E=(1.720743)\dfrac{4}{\sqrt{22}}=1.46745456106\approx1.467

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467

Do you know the inequality? Please explain and show answer :)
DerKrebs [107]
If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .

(1) u have an open circle on -7 with shading to the left....
     x < -7

(2) u have a closed circle on 4.5 with shading to the left....
    x < = 4.5 (thats less then or equal)

(3) u have an open circle on -5 with shading to the right...
     x > -5

(4) u have an open circle on 1.5 with shading to the right...
     x > 1.5
