The slope-intercept form: y = mx + b

m-the slope

$\dfrac{x}{-1}+\dfrac{y}{6}=1\\\\-x+\dfrac{y}{6}=1\ \ \ \ |add\ x\ to\ both\ sides\\\\\dfrac{y}{6}=x+1\ \ \ \ |multiply\ both\ sides\ by\ 6\\\\y=6x+6\\\\\\Answer:\boxed{The\ slope\ m=6}$

Words were displayed on a computer screen with background colors of red and blue. Results from scores on a test of word recall a

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.

$H_0: Means are equal\\H_a: Means are not equal$

(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
