The answer would be 5227. If you subtract what is in parenthesis first and then multiply it that should be your answer.

Answer: $5,227$

Step-by-step explanation:

Given the expression $63*83-(6-4)$ you can simplify it by applying these steps:

First, make the subtraction of the numbers that are inside of the parentheses:

$=63*83-(2)$

Apply multiplication of signs to eliminate the parentheses. Remember that:

$(-)(-)=+\\(+)(+)=+\\(-)(+)=-$

Then:

$=63*83-2$

Now, make the multplication indicated:

$=5,229-2$

Finally, subtract both numbers:

$=5,227$

Answer:

The test statistic for Norah's test is $t = -2$

Step-by-step explanation:

Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.

This means that at the null hypothesis we test if the sample mean is 500 ml, that is:

$H_0: \mu = 500$

At the alternate hypothesis, we test if it is differente than 500 ml, that is:

$H_a: \mu \neq 500$

The test statistic is:

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
