Mr Seinfeld owns three restaurants. Lately, he has been receiving several complaints about the cleanliness of his restaurants. John, one of his employees who has taken a business analytics class in his college years, was given the task of conducting a statistical test to determine if cleanliness among the restaurants is different. He recruited five fellow workers to serve as inspectors and their role is to grade the restaurants on a scale of 0 to 100. The results of their inspection are available in the following link:
Inspector Restaurant 1 Restaurant 2 Restaurant 3
Sinjini 72 54 84
Laura 68 55 85
Dawit 73 59 80
Michael 69 60 82
Thuy 75 56 84
John will the inspectors as blocks when conducting ANOVA test. He will also use a 5% level of significance when conducting hypothesis testing.
What is the main null hypothesis implied in this problem?
a. μ(1)=μ(2)=μ(3)=μ(4)=μ(5)
b. μ(1)=μ(2)=μ(3)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer: the correct answer is -32
