Solve (9^62773 + 2)^83721

shutvik [7]

Remember the order of operations and do what is in parenthses first.

Take 9 to its power first, then add 2. Once you get that, take that answer to the 83721 power.

I would give you the answer, but my calculator is saying invalid input every time I am trying to use such high exponents. Sorry :( But I hope that this helps

A random sample of n D 225 and xN D 21 was drawn from a normal population with a known

Rainbow [258]

Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.
