Suppose the following data were collected from a sample of 15 ceos relating annual salary to years of experience and the economic sector their company belongs to. use statistical software to find the following regression equation: salaryi=b0+b1experiencei+b2servicei +b3industriali+ei. is there enough evidence to support the claim that on average, ceos in the service sector have lower salaries than ceos in the financial sector at the 0.05 level of significance? if yes, write the regression equation in the spaces provided with answers rounded to two decimal places. else, select "there is not enough evidence."

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

answer: i wpould go with c

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
