In a large class of introductory Statistics students the professor has each person toss a coin 20 times and calculate the proportion of their tosses that were heads Complete parts a through d below a Confirm that you can use a Normal model here The Independence Assumption The Success Failure Condition Type integers or decimals Do not round b Use the 68 95 99 7 Rule to describe the sampling distribution model satisfied because the sample proportions satisfied because np The Independence Assumption The Success Failure Condition Type integers or decimals Do not round Use the graph below to describe the sampling distribution model independent of each other since one sample proportion 10 and nq which are both and about 95 between and and about 99 7 between and About 68 of the students should have proportions between Type integers or decimals rounded to four decimal places as needed Use ascending order c They increase the number of tosses to 32 each Draw and label the appropriate sampling distribution model Check the appropriate conditions to justify your model Range A Range B Range C satisfied because the sample proportions satisfied because np and nq which are both p hat independent of each other since one sample proportion 10 Q qui Q another sample proportion another sample proportion
