The right to vote (and not to wait) In the past decade, two presidential elections in the United States have witnessedvery long wait times at precincts (voting stations) in states that ultimately decidedthe election (Florida in 2000 and Ohio in 2004).In Philadelphia as well, some voters complained about the long lines in someprecincts, with most complaints coming from precinct A. In 2004, the averagenumber of voters arriving at Precinct A was 35 per hour and the arrivals of voterswas random with inter-arrival times that had a coefficient of variation of 1 (CVa=1).Philadelphia deployed 1 voting machine in Precinct A. Suppose that each voterspent on average 100 seconds in the voting booth (this is the time needed to casther/his vote using a voting machine), with a standard deviation of 120 seconds.

Globally, 35% of all ridged brittleshell tortoises have spots on their shells. A herpetologist in Citition collects a sample of 38 ridged brittlesell tortoises and finds that 16 of them have spots on their shells. The herpetologist would like to test the claim that the proportion of ridged brittleshell tortoises in Cititon with spots on their shells is greater than 35%. The herpetologist ends up rejecting the null hypothesis. If the actual proportion of ridged brittleshell tortoises in Cititon with spots on their shells is 41%, then what type of error, if any, has occurred? In the problem above, what is the test statistic?
