C because you multiply the big number with the lower number then you add the number on top. 3 times 3 equals 9 plus 2 = 11. you keep the bottom number under your new number
Answer:
The <em>p</em>-value of the test is 0.0512.
Step-by-step explanation:
The <em>p</em>-value of a test is well-defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was the truly observed value of the test statistic.
In this case the output of the t-test_ind method from scipy module is provided as follows:
Output = (-1.99, 0.0512)
The first value within the parentheses is the test statistic value.
So the test statistic value is, -1.99.
And the second value within the parentheses is the <em>p</em>-value of the test.
So the <em>p</em>-value of the test is 0.0512.
Ok you’ll know that it’s 0.31%
Explanation:
The process is start by making it into a fraction, 2/650 then divide 2 by 650 to get 0.0031 (I rounded up) which to make it into a percentage, you move everything two spot closer to the “.”
0.31 then add a % and bam that’s the answer.
Hope this helps!
