A survey of 15651565 people who took trips revealed that 151151 of them included a visit to a theme park. Based on those survery results, a management consultant claims that less than 1111 % of trips include a theme park visit. Test this claim using the α=0.01α=0.01 significance level. The test statistic is The critical value is The conclusion is

According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.34. Suppose a random sample of 106 traffic fatalities in a certain region results in 48 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the a= 0.01 level of significance? ....

The sales rep of a waterbed claims that 25% of the Filipino died because of cardiovascular diseases. A researcher wants to test this claim. A hospital record shows that out of a random sample of 200 dead patients, 55 patients died because of cardiovascular diseases. Does the data provide sufficient evidence to support the claim of the sales rep? Use 0.03 level of significance.
Suppose that 90 of 100 patients who enter hospital A with a particular ailment recover, while 160 of 200 patients who enter hospital B with the same ailment recover. Does this sample information provide strong evidence that recovery rate for the disease is significantly dependent on the hospital (at the .05 level)? Perform the appropriate test of significance to justify your answer, and provide a one- or two-sentence conclusion.
