Question
Past studies have indicated that the percentage of smokers was estimated to be about 35%. Given the new
smoking cessation programs that have been implemented, you now believe that the percentage of smokers
has reduced. You randomly surveyed 1714 people and found that 562 smoke. Use a 0.05 significance level to
test the claim that the percentage of smokers has reduced.
a) Identify the nult and alternative hypotheses?
Ho:? V
H.:? v
b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)?
O left-tailed
Oright-tailed
O two-tailed
c) Identify the appropriate significance level.
d) Calculate your test statistic. (Round your final answer to two decimal places.)
e) Calculate your p-value. (Round your final answer to four decimal places.)
f) Do you reject the null hypothesis?
O We reject the null hypothesis, since the p-value is less than the significance level.
O We reject the null hypothesis, since the p-value is not less than the significance level.
O We do not reject the null hypothesis, since the p-value is less than the significance level.
O We do not reject the null hypothesis, since the p-value is not less than the significance level.
g) Select the statement below that best represents the conclusion that can be made.
O There is sufficient evidence to warrant rejection of the claim that the percentage of smokers is less
than 35%.
O There is not sufficient evidence to warrant rejection of the claim that the percentage of smokers is
less than 35%.
O The sample data support the claim that the percentage of smokers is less than 35%.
O There is not sufficient sample evidence to support the claim that the percentage of smokers is less
than 35%
