Rakesh wants to know if the average adequate yearly progress (AYP) from the classes in his school are higher than the average AYP of all students in Orange County (\muμ = .65). What type of t-test should he use to answer this question
○ Related samples t-test
○ Independent samples t-test
○ or Single sample t-test

Rakesh wants to know if the average adequate yearly progress (AYP) from the classes in his school are higher than the average AYP of all students in Orange County (\muμ = .65).

The independent samples t-test should be used to answer the question.

Step-by-step explanation:

Based on the information in the question given, both samples are independent of each other, also two sample sizes were obtained from each of the schools, therefore the independent samples t-test should be used to answer the question given.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
