Question
Previous research showed that 15% percent of teenagers between the ages of 13 and 17 smoke. A study was conducted to examine the current proportion of US teenagers between the ages of 13 and 17 who smoke. A survey asked a random sample of 785 teenagers between the ages of 13 to 17 if they smoke. 71 of the surveyed teenagers responded that they smoke. The information above is for the question below.
Assuming the requirements are met for the teenage smoking study, state the null and alternative hypothesis for testing the claim that the proportion of US teenagers between the ages of 13 and 17 who smoke has decreased. O Ho: p < 0.15 H₂ : p= 0.15 O Ho: p = 0.15 H₂ : p < 0.15 O Ho: p > 0.15 H₂ : p = 0.15 Ho: p = 0.15 H₂ :p> 0.15 Hop 0.15 H₂ : p = 0.15 Ho: p = 0.15 Ha : p = 0.15
