Hi, i'm david and i'm here to have jans from the question.
00:03
Now let me put up the question here.
00:07
In the question here, we are going to discuss about the high -body testing.
00:12
I'm going to find the b value from the test on the significance.
00:16
And here, the correlation coefficient between the fat content and the calories in determining to be the 0 -17.
00:25
And it will be the r equal to the minus 017.
00:31
We have the n equals to the 25 and the first thing we will need to write down the noon hypothesis the row equal to the 0 versus the alternative hypothesis role will not equal to the 0 so therefore the first time we need to find will be the test statistics denoted by the t the formula will be the r minus 2 if we'll look in the value we have the 0 1 1 divided by the square root to the 1 minus 0 .17 square divided by n equals 25 minus 2.
01:09
So it will compute this one, 1 minus z squared, divided by the 23 square root of the 107 equals to the minus 0 .17.
01:24
And then it would equal to the minus 4 .7.
01:31
The next time we need to find the p value...
