A police department released the numbers of calls for the different days of the week during the month of October, as shown in the table to the right. Use a 0.01 significance level to test the claim that the different days of the week have the same frequencies of police calls. What is the fundamental error with this analysis?

The City of South Lake Tahoe, CA, has an Asian population of 1,419 people, out of a total population of 23,609. Suppose that a survey of 1,419 self-reported Asians in the Manhattan, NY, area yielded the data in the table below. Conduct a goodness-of-fit test to determine if the the self-reported sub-groups of Asians in the Manhattan area fit that of the Lake Tahoe area. (Use a significance level of 0.05.) Race Lake Tahoe Frequency Manhattan Frequency Asian Indian 131 174 Chinese 118 557 Filipino 1,045 518 Japanese 80 54 Korean 12 29 Vietnamese 9 21 Other 24 66 State the distribution to use for the test. What is the test statistic? (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.)
The production numbers from four different machines with the same features in three different factories are given in the table below. In the hypothesis test of whether there is a difference between the production numbers of factories and machines at the 5% significance level, which of the following is approximately the mean square error (SR) value?
Since instant replay was introduced in tennis, men challenged 3057 calls, and 572 were overturned. Women challenged 1312 calls, and 336 were overturned. Use a 0.01 significance level to test the claim that women have more success in challenging calls than men.
A grassroots group opposed to a proposed increase in the gas tax claimed that the increase would hurt working-class people the most, since they commute the farthest to work. Suppose that the group randomly surveyed 24 individuals and asked them their daily one-way commuting mileage. The results are in Table below. Using a 5% significance level, test the hypothesis that the three mean commuting mileages are the same. working-class professional (middle incomes) professional (wealthy) 17.8 16.5 8.5 26.7 17.4 6.3 49.4 22.0 4.6 9.4 7.4 12.6 65.4 9.4 11.0 47.1 2.1 28.6 19.5 6.4 15.4 51.2 13.9 9.3
An online poll asked: "Do you believe the Loch Ness monster exists?" Among 20 comma 47820,478 responses, 6969% were "yes." Use a 0.050.05 significance level to test the claim that most people believe that the Loch Ness monster exists. How is the conclusion affected by the fact that Internet users who saw the question could decide whether to respond?
