Question

The lengths of time (in years) it took a random sample of

former smokers to quit smoking permanently are listed. Assume the population standard deviation is

6.1

years. At

alphaαequals=0.01,

is there enough evidence to reject the claim that the mean time it takes smokers to quit smoking permanently is

years? Complete parts (a) through (e).

18.4	16.7	11.1	15.8	18.8	21.8	21.8	14.8
14.8	9.7	15.8	9.9	9.9	7.6	22.5	14.1
22.2	14.4	13.6	7.5	9.2	20.7	12.7	8.3
16.1	13.1	22.9	13.2	16.1	12.4	12.6	14.1

(a) Identify the claim and state the null hypothesis and alternative hypothesis.

Upper H0:

mu equals=13

(claim)

Upper Ha:

mu not equals≠13

Upper H0:

mu greater than or equals≥13

(claim)

Upper Ha:

mu less than<13

Upper H0:

mu not equals≠13

(claim)

Upper Ha:

mu equals=13

Upper H0:

mu greater than>13

(claim)

Upper Ha:

mu less than or equals≤13

Upper H0:

mu less than or equals≤13

(claim)

Upper Ha:

mu Greater than>13

Upper H0:

mu greater than>13

Upper Ha:

muμless than or equals≤13

(claim)

(b) Identify the standardized test statistic. Use technology.

zequals=(Blank)

(Round to two decimal places as needed.)

Pequals=(Blank)

(Round to three decimal places as needed.)

(d) Decide whether to reject or fail to reject the null hypothesis and (e) interpret the decision in the context of the original claim at the

11%

level of significance.
