Hello, I hope this helped and that I was right, have a nice day.
Hi I couldn’t do the work for the surface area on the picture because I didn’t have space left so here it is,
Formula: 2(lw+lh+wh)
Shape 1
(2.4 x 1.1) + (2.4 x1.8) + (1.1 x 1.8)= 8.94
8.94 x 2= 17.88
Shape 2
(2.4 x 1.1) + (2.4 x 0.5) + (1.1 x 0.5) = 4.39
4.39 x2 = 8.78
17.88+ 8.78

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
