The average local cell phone call length was reported to be 2.27 minutes. a random sample of 20 phone calls showed an average of 2.98 minutes in length with a standard deviation of 0.98 minute. at α=0.05, can it be concluded that the average differs from the population average?

5104.38 inches

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

if you are factoring then 4(x+3)

if you are simplifying 4x+12
