To solve these problems simply place a denominator of 1, for all of the whole numbers and then multiply the top numbers together and then the bottom ones.
So for the first one, it would be 4 • 500/1 • 5
2000/5 = 400.
This is the answer.
It's A and C, I've taken a test that has this question and it was correct when I answered this, so A and C is your answer.
Step-by-step explanation:
I think the answer is x=-4,x=+6
Answer:
The critical value is
Step-by-step explanation:
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 = 8 - 1 = 7
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 7 degrees of freedom(y-axis) and a confidence level of . So we have T = 1.415.
The critical value is
There's nothing below to select it from. I looked.
