Unsure how to start part B, cant find any examples in my textbook.

A study examined a random sample of smokers who tried to quit smoking by using either the patch or e-cigarettes in 2012. Here is a quote from a news article referencing the study: “Quitting is hard. The number of people who quit (within 6 months) was low overall—just 38 of the 584 smokers given the e-cigarette or the patch.”

B)In 2010, it was reported that the proportion of smokers who quit smoking by using either the patch or e-cigarettes within 6 months in the population was 5%. Using the current data in 2012, test the claim that the proportion of smokers who quit smoking by using either the patch or e-cigarettes in the population has declined since 2010. Useall stepsfor hypothesis testing to make a conclusion at a significance level of 10%.
