Therefore, slope the line given in the graph attached will be,
Slope = 
= -2
Slope = -2

Step-by-step explanation:
The score increase was 35 points. They claimed an increase of at least 50 points. For a significance level of 5%, the z-score for the situation needs to be at smaller than -1.645. For a significance level of 1%, the z-score needs to be smaller than -2.325
The z score for our situation: z = (385 - 350)/50 = 0.7
The average score of 385 of Tutor O-Rama scores is not significantly different from the average of the other students SAT scores. The evidence doesn't support their claim of being effective tutoring.
