Question 1: A researcher is interested in whether certain lifestyle factors that are related to indoor air quality may increase the risk of very severe asthma in children. He believes he may gain some information in this regard comparing the homes of children who have 1 admission only to a hospital for asthma to the homes of children who are readmitted within 3 months after their previous admission for asthma. From the same hospital he invites a random selection of children who had one admission only and a random selection of children who had a readmission. For the pilot study a questionnaire records, along with many other factors, the time spent, in hours, In using the vacuum cleaner per week in 6 homes in each of the two groups of children. This is the data: Readmitted group: 1.25, 2.25, 2.25, 2.75, 3, 3.5 Non-Readmitted group: .5, .75, 1, 1.25, 1.25, 2.75 i. What is the mean, median, standard deviation and IQR for the re-admitted group? ii. What is the mean, median, standard deviation and IQR for the nonreadmitted group? iii. Would you say vacuuming times within the two groups are normally distributed? Explain your reasoning. iv. The hypothesis we wish to test is below. What statistical test would you use? Ha: There is no difference in the means of the two groups. H1: There is a difference in the means. v. What is the p-value associate with the test statistic? vi. What is the 95% CI for the difference in means? vii. Interpret the results of this analysis. viii. What are the short failings of this analysis? Explain in terms of validity and reliability
