Rewrite the following multiplication problem using a

Reil [10]

Well uh first let's find the value of the problem, 1/2 * 2/3 * 4/5 = 4/15. Then we need to apply associative property 1/2(2/3*4/5). we do 2/3 * 4/5 first, we get 8/15. Then we multiply 8/15 by 1/2 = 4/15. We applied associative property and we still got the same results as without any properties applied.

Answer:

$6 \pm 2.861(0.3354)$

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 20 - 1 = 19

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.99}{2} = 0.995$ . So we have T = 2.861.
