Question

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

3232

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

6.56.5

years. At

alphaαequals=0.10.1,

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

1313

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

19.7	20.5	7.7	18.6	10.5	8.8	17.7	16.2
21.2	18.4	16.4	9.7	9.3	16.8	11.1	21.3
8.5	12.6	21.2	11.3	21.7	21.5	11.9	16.1
15.9	7.1	18.5	7.1	14.1	22.7	9.2	17.9

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

Upper H 0H0:

muμgreater than>13

Upper H Subscript aHa:

muμless than or equals≤13

(claim)

Upper H 0H0:

muμgreater than or equals≥13

(claim)

Upper H Subscript aHa:

muμless than<13

Upper H 0H0:

muμless than or equals≤13

(claim)

Upper H Subscript aHa:

muμgreater than>13

Upper H 0H0:

muμnot equals≠13

(claim)

Upper H Subscript aHa:

muμequals=13

Upper H 0H0:

muμgreater than>13

(claim)

Upper H Subscript aHa:

muμless than or equals≤13

Upper H 0H0:

muμequals=13

(claim)

Upper H Subscript aHa:

muμnot equals≠13

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

zequals=nothing

(Round to two decimal places as needed.)

Pequals=nothing

(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

10%

level of significance.
