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
3^3. if you're simplifying then you keep the base the smae but add the exponents since you are "multiplying" the bases
Add August and September for total amount of bushels:
46,100 + 8,120 = 54,220 total bushels
Divide total bushels by total acres:
54,220 / 488 = 111.1 = 111 bushels per acre
