Answer:
Yes, the background color appear to have an effect on the variation of word recall scores
Step-by-step explanation:
Given that results from scores on a test of word recall are given are as follows:
Two test scores have independent means and having normal distribution.
(Two tailed test at 5% significance level)
Group Group One Group Two
Mean 15.1400 12.4200
SD 5.9100 5.4200
SEM 0.9990 0.8910
N 35 37
The mean of Group One minus Group Two equals 2.7200
standard error of difference = 1.335
Hence t statistic = 2.0369
p value = 0.0454
Since p <0.05 we reject null hypothesis
Yes, the background color appear to have an effect on the variation of word recall scores
Step-by-step explanation:
Hey there!
We know that the slope intercept is; y = mx+b.
Where "m" represents the slope. And "b" represents the y-intercept.
Example:
If the question is as; y = 3x +8
Then your slope of the slope intercept form is "3" where as "8" is y-intercept.
So, the variable"m" represents the slope.

Answer: B, $330
_____
$165 (20hours) x 2 = $330 (40hours)
Answer:
Step-by-step explanation:
Given:
- Center = (5,2)
- Endpoint = (8,6)
First, find radius via distance between center and endpoint. The formula of distance between two points is:
Determine:
Hence:
Therefore, the radius is 5.
Then we can substitute center and radius in circle equation. The equation of a circle is:
Our center is at (h,k) which is (5,2) and radius beings 5.
Hence, your answer is:
9.44882 now round to the nearest tenth
