Question

100%

In one study of smokers who tried to quit smoking with nicotine path therapy,

were smoking one year after the treatment, and 32 were not smoking one year after the treatment. Use a 0.10 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking a year after the treatment.

a. Define the parameter

= The mean number of smokers who used the patch and were smoking a year after the treatment

p = The proportion of all smokers who used the patch and were smoking a year after the treatment

p = The proportion of all smokers who used the patch and were not smoking a year after the treatment

= The proportion of all smokers who used the patch and were smoking a year after the treatment

b. State the null and alternative hypotheses

Upper H 0 : p equals 0.50 Upper H 1 : p greater than 0.50

Upper H 0 : p greater than 0.50 Upper H 1 : p equals 0.50

Upper H 0 : p equals

Upper H 1 : p less than

Upper H 0 : mu not equals 0.50 Upper H 1 : mu equals 0.50

c. Calculate the sample proportion

ModifyingAbove p with caret

Which of these options is closest to its value?

0.7552

0.3633

0.5715

0.5616

d. Calculate the test statistic. Which of these options is closest to its value?

0.96

negative 0.98

1.23

1.05

e. Calculate the P-value. Which of these options is closest to its value?

0.2397

negative 0.0404

0.1469

0.0456

f. State the technical conclusion

Reject Upper H 0

Do not reject Upper H 0

g. State the final conclusion

There is not sufficient evidence to warrant rejection of the claim.

There is sufficient evidence to warrant rejection of the claim.

There is not sufficient sample evidence to support the claim.

The sample data support the claim.

h. Do these results suggest that the nicotine patch therapy is ineffective?

Yes
