In advance of the 1936 Presidential Election, a magazine titled Literary Digest released the results of an opinion poll predicting that the republican candidate Aif Landon would win by a large margin. The magazine sent post cards to approximately 10,000,000 prospective voters. These prospective voters were selected from the subscription list of the magazine, from automobile registration lists, from phone lists, and from club membership lists. Approximately 2,300,000 people returned the postcards. a. Think about the state of the United States in 1936. Explain why a sample chosen from magazine subscription lists, automobile registration lists, phone books, and club membership lists was not representative of the population of the United States at that time. b. What effect does the low response rate have on the reliability of the sample? c. Are these problems examples of sampling error or nonsampling error? d. During the same year, George Gallup conducted his own poll of 30,000 prospective voters. These researchers used a method they called quoa sampling’ to obain survey answers from specific subsets of the population. Quota sampling is an example of which sampling method described in this module?

The city of Wonderland has 12000 registered voters. There are two candidates for city council in an
upcoming election: Misty and Pikachu.
The day before the election, a telephone poll of 350 randomly selected registered voters was conducted.
113 said they'd vote for Misty, 216 said they'd vote for Pikachu, and 21 were undecided.
(a) Find the statistic for the proportion of voters surveyed who said they'd vote for Misty. Answer as a
fraction or decimal, rounded to 4 places if necessary.
(b) Fill in the blank below.
The statistic above suggests that we could expect
of the 12000
registered voters to vote for Misty.
An American study published in a recent year claimed to find evidence of voting by noncitizens. The conclusion was based largely on a survey several years prior in which approximately 38,000
registered voters were asked both whether they voted and whether they were citizens. A total of 339 of those surveyed reported being noncitizens, and a total of 48 of these people also said
they voted. Complete parts (a) through (d) below.
a. Based on the survey, what percentage of noncitizens claim to have voted?
7%
(Round to the nearest whole number as needed.)
