The length of time in years it took a random sample of 30 former smokers to quit smoking permanently are listed below. At a= 0.08 is there enough evidence to reject the claim that the mean time it takes smokers to quit smoking permanently is 15 years? Using critical values. 15,13,22,13 10 18 14 7 17 8 22 12 19 14 16 10 32 15 18 12 18 22 7 8 20 7 12 10 9 10

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
