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
Yesss ur answer is correct
Hello there! The lines between the numbers represent absolute value. In case you don't know, absolute value is the distance from 0, and it is always positive. For this, the absolute value of -6 is 6 and the absolute value of -0.4 is 0.4. 6 + 0.4 is 6.4. There. You chose the right answer choice. The answer is 6.4.
Answer:
738 messages
Step-by-step explanation:
Use the given information to set up an equation. 7 is constant and 0.3 per message, with a total of 18.40.
0.3x + 7 = 18.4
Now solve for x
0.3x = 11.4
x = 38
