Answer:
A) Reject the null hypothesis and conclude that chocolate affected mood because zero, or no effect, does not fall within the confidence interval
Step-by-step explanation:
The confidence interval could be used as a tool to test an hypothesis on a some certain conditions. When we obtain a confidence interval whose range includes the value 0, we would fail to reject the null hypothesis of such analysis as this upholds the truth of the null hypothesis. However, if the interval does not contain the value 0, we reject the null and claim that there is significant evidence to accept the alternative hypothesis.
Hence, for the confidence interval given [2.34, 5.41], the interval does not contain the value 0, Hence, we reject the null.
Hello!
First you have to find the area of the bigger square
When it goes from the center to a corner you multiply the value by 2 to find one side
9 * 2 =18
Now you find the area
18 * 18 = 324
Now we find the area of the smaller region
4 * 2 = 8
Find the area
8 * 8 = 64
Now we subtract these
324 - 64 = 260
The answer is 260
Hope this helps!
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = ( a + b ) ( a − b ) where a = 7 and b = a + x . − ( 7 + a + x ) ( a + x − 7 )
(264 1/4) / (13 1/2)
you get 19 31/54 mpg
