Answer:20 pints of blue paint and 8 pints of yellow paint
Step-by-step explanation:
5 pints of blue and 2 pints of yellow make 7 pints of green. (5 + 2 = 7)You must do this four times to get 28 pints of green. (4 · 7 = 28)So you need 20 (4 · 5) pints of blue and 8 (4 · 2) pints of yellow.
Answer:
To test whether or not the population regression function is linear rather than a polynomial of order r, use the test of (minus1) restrictions using the F Minus Statistic.
Therefore, option D is the correct answer choice.
Step-by-step explanation:
The test of (r-1) restrictions using the F statistic is the most effective way to test whether or not the population regression function is linear rather than a polynomial of order r.
Therefore, 'use the test of (minus1) restrictions using the F Minus Statistic', option D is the correct answer choice.

WORKINGS
Given the data set for 11 seasons of play14, 22, 19, 21, 30, 32, 25, 15, 16, 27, 28
Quartiles (usually 3 in number; Q1. Q2 and Q3) divide a rank-ordered data set into four equal parts
14, 22, 19, 21, 30, 32, 25, 15, 16, 27, 28
First order the data set by rank
12, 14, 16, 19, 21, 22, 25, 27, 28, 30, 32
Q1 is the first quartile
Q2 is the second quartile
Q3 is the third quartile
Interquartile range = Q3 – Q1
The median value in the set, Q2 = 22
First half of the rank-ordered data set is therefore 12, 14, 16, 19, 21
While the Second half of the rank-ordered data set is 25, 27, 28, 30, 32
The median value in the first half of the set, Q1 = 16
The median value in the second half of the set, Q3 = 28
Interquartile range = Q3 – Q1
Therefore, interquartile range = 28 – 16
= 12
The interquartile range of the data is 12
