Please have all 6 steps of the p method listed clearly! thank youuuu Schools and museums: Do people who are interested in environmental issues visit museums more often than people who are not? The General Social Survey asked 990 people how interested they were in environmental issues, and how often they had visited a science museum in the past year. The following table presents the results. Number of Visits None One More Than One Very interested 331 96 40 Moderately interested 347 57 25 Not interested 70 15 9 Can you conclude that the number of visits to a science museum is related to interest in environmental issues? Use the α = 0.01 level of significance.
Explain the method of retrospective study for collecting data. Consider the semiconductor wafer data in Table 4. Suppose those 10 wafers are selected randomly (without replacement) for an electrical test. Determine the probability that exactly 4 wafers have high contamination.
