Answer: Her account would earn $17.5

Step-by-step explanation: The earning on a given amount with simple interest can be computed as follows;

Interest = PRT/100

Where P is the principal (initial amount), R is the rate of interest and T is the number of years. The formula now becomes,

Interest = (50 x 3.5 x 10)/100

Interest = 1750/100

Interest = 17.5

Therefore, in 10 years her account would have earned $17.5

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
