alukav5142 [94]

Answer:

R1,380

H0: μ ≥ 5.4

H1 : μ < 5.4

F.)

If Pvalue < α ; Reject H0

G.)

Test statistic :

(xbar - μ) ÷ (s/sqrt(n))

(4.5 - 5.4) ÷ (2.7/sqrt(80))

-0.9 ÷ 0.3018691

= - 2.98

H.)

Pvalue fro Zscore calculator, α = 0.10 = 0.002882

I.)

Decision :

0.002882 < 0.10

Since, Pvalue < α ; We reject the Null

J.)

We Can conclude that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced

Simplify, no negative<br> exponents.<br> -40x²y<br> -8x²y
Kamila [148]

Answer:

5x^5

y^4

Step-by-step explanation:

-40 ÷ -8 = 5. Then subtract x to the 2nd from x to the 7th, which is x to the 5th. And once you do the same with y, you get y to -4. But since there can't be any negative exponents, you bring that down, giving you the final answer.
