Adult entrance fees to amusement parks in the United States are normally distributed with a population standard deviation of 2.5

kondor19780726 [428]

Answer: 1.509

Step-by-step explanation:

The formula of Margin of Error for (n<30):-

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

Given : Sample size : n= 22

Level of confidence = 0.99

Significance level : $\alpha=1-0.99=0.01$

Using the t-distribution table ,

Critical value : $t_{n-1, \alpha/2}=t_{21,0.005}= 2.831$

Standard deviation: $\sigma=\text{ 2.5 dollars }$

Then, we have

$E=( 2.831)\dfrac{2.5}{\sqrt{22}}\approx1.509$

Hence, the margin of error for a 99% confidence interval for the population mean =1.509

2 x 1’- 2 3/8” = ? <br> Please help

Nat2105 [25]

Answer:

$=-\frac{3}{8}$ is the answer.

Step-by-step explanation:

We have to solve the given expression 2 × 1 - 2 3/8

$2\times 1-2\frac{3}{8}$

$=\frac{2}{1}-\frac{19}{8}$ [Now we take LCF of denominators of both the fractions]

$=\frac{(16-19)}{8}$

$=-\frac{3}{8}$

So the final answer is $=-\frac{3}{8}$
