Answer:
y = -17
Step-by-step explanation:
5 + 3(y - 4) = 5(y + 2) - y Distribute
5 + 3y -12 = 5y + 10 - y Combine like terms
-7 + 3y = 4y + 10
+7 +17 Add 17 to both sides
3y = 4y + 17
-4y -4y Subtract 4y from both sides
-y = 17 Divide both sides by -1
y = -17

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
