Answer:

Step-by-step explanation:

Given the 2 equations

2x + 3y = 9 → (1)

- 2x + 2y = 6 → (2)

Adding the 2 equations term by term will eliminate x

(2x - 2x) + (3y + 2y) = (9 + 6), that is

5y = 15 ( divide both sides by 5 )

y = 3

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
