When conducting a hypothesis test, out of 25 total turns on my route to work I found that 13 were right hand turns. using probability=.10 determine if the true proportion of right hand turns is actually equal to (.50) Are there legitimate factors which would make a driver have a larger or smaller proportion of right-hand turns?Answer by stanbon(57290)   (Show Source): You can put this solution on YOUR website!When conducting a hypothesis test, out of 25 total turns on my route to work I found that 13 were right hand turns. using probability=.10 determine if the true proportion of right hand turns is actually equal to (.50) Are there legitimate factors which would make a driver have a larger or smaller proportion of right-hand turns? --------------- Ho: p=0.5 Ha: p not equal to 0.5 -------- n=25 x=13 p-hat=13/25=0.52 Critical Values are +1.645 and -1.645 Test Statistic = z=0.2 p-value=.84 Since p-value is greater than alpha=0.10 Fail to reject Ho. Conclusion: Right and left turns are about 50%/50% Cheers, Stan H.
