Tutor O-Rama claims that their services will raise student SAT math scores at least 50 points. The average score on the math por
Novosadov [1.4K]

Answer:

See below

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.

10a+6x-2a-3x

In order to find the answer, we combine like terms and then simplify.

3x+8a

Hope this helps.
