How likely are the results of your funding for education is sample if the population proportion of voters in the town in favor of the referendum is 0.49? Based on your result, comment on the dangers of using exit elections polling to call How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.497 The probability that more than 108 people voted for the referendum is Round to four decimal places as noedod.) Comment on the dangers of using exit polling to call elections. Choose the correct anower below OA.

Thus, it is not unusual for a O D. The result is not unusual because the probability that p is equal to or more extre than the sample proportion is greater than 5%. Thus, it is not unusual for a Click to select your answerís)

Explanation / Answer

here mean number of in favour of referendum =np=200*0.49=98

and std deviation =(np(1-p))1/2 =7.0697

hence probability of more than 108 people voted in referendum =P(X>108)=1-P(X<=108)

=1-P(Z<(108.5-98)/7.0697)=1-P(Z<1.4852)=1-0.9313 =0.0687

option D is correct
