The mean age when smokers first start is 13 years old with a population standard deviation of 2 years. A researcher thinks that smoking age has significantly changed since the invention of ENDS-electronic nicotine delivery systems. A survey of smokers of this generation was done to see if the mean age has changed. The sample of 34 smokers found that their mean starting age was 12.3 years old. Do the data support the claim at the 1% significance level? What are the correct hypotheses? Hoi years Enter an integer or decimal number [more..] H₁: P ? ~ years Based on the hypotheses, find the following: Test Statistic z = (Round to 4 decimal places.) Critical Values = ± Based on the above we choose to Select an answer that the mean age The correct summary would be: Select an answer smokers first start is different than 13. (Round to 2 decimal places.)
