Okay, so i see that you need help with this question and so it wants you to use the 0 .01 significance level to answer the following.
00:08
So it wants to know the critical r value for the hypothesis test.
00:12
So in order to find the critical value and then the correlation coefficient of this data set, so for the zero point i'm using, excuse me, i'm using, sorry about that, i am using excel strictly as a calculator.

You can totally follow along with paper and pencil, but the first thing i'm going to do is i'm going to find out what 1 minus 0 .01 divided by 2 is, and that's 0 .995, okay? and so then what i'm going to do is i'm going to take t 0 .995 and then with 24 as your degree of freedom, because what you have to do is you have to take, there is a total of 13 numbers in each column, so you do 13 plus 13 minus 2 and that's 24, and so then that equals 2 .7969, and let me just merge this, come on, okay? and so it's going to be the plus or minus this, so the critical value, plus or minus, rounded to, it doesn't say, 2 .7969, and then i'm going to bold and merge this...
