- What is a sample space?What is meant by the sample space of an experiment?The American Water Works Association reports that, The average household water usage is more than 10 gallons per day. However, in a pandemic like this, it is suspected that there is a change in household water consumption. A researcher conducted a survey and took samples of 12 household heads and asked about the use of the gallon water. The data obtained are as follows: 74, 8, 13, 17, 13, 15, 12, 13, 15, 16, 9, 7. If it is known that the data is normally distributed. Use a significance level of 5% to test whether the average household water use has increased (greater than 10 gallons)? What will happen if the household's water use increases by 5% from the previous one? Analyze your answer and come up with a conclusion!
- Are there less children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban areas over states that are mostly rural? Assume data were collected from a fairly urban state and they found 167 eight-year olds diagnosed with ASD out of 18922 eight-year olds evaluated. Assume data were then collected for a fairly rural state and they found 68 eight-year olds diagnosed with ASD out of 2989 eight-year olds evaluated. Is there enough evidence to show that the proportion of children diagnosed with ASD in the fairly urban state is lower than the proportion in the fairly rural state? Test at the 3% level and Compute a 94% confidence interval for the difference in proportions. (round to 3 decimal points)Wertheretal et al. examined the β-leucocyte count (/ L) in 51subjects with colorectal cancer and 19 healthy controls. The cancer patients were also classified into Dukes’s classification (A,B,C) for colorectal cancer that gives doctors a guide to the risk, following surgery, of cancer coming back or spreading to other parts of the body. An additional category (D) identified patients with disease that had not been completely resected. The results are displayed in the following table. Perform an analysis of these data in which you identify the sources of variability and specify the degrees of freedom for each. Do these data provide sufficient evidence to indicate that, on average, leucocyte counts differ among the five categories? Let α=0.01 . Write the null and alternative hypotheses of this study. Test the claim using the ANOVA Table. If you reject the null hypothesis, interpret your results using multiple comparison test Bonferroni. What assumptions must be made in part (b)?

For one part of the survey, the 358 providers were classified according to case load (number of abortions performed per year) and whether they permit their patients to take the abortion drug misoprostol at home or require the patients to return to the abortion facility to receive the drug. The responses are summarized in the accompanying table. Suppose we select, at random, one of the 358 providers and observe the provider's case load (fewer than 50, or 50 or more) and home use of the drug (yes or no). Number of Abortions Permit Drug at Home Fewer than 50 50 or more Totals Yes 170 130 300 No 48 10 58 Totals 218 140 358 a.

Make sure you state the statistical hypotheses and conclusions, as well as the biological conclusions.The manufacturer of a sports car claims that the fuel injection system lasts at least 48 months before it needs to be replaced. A consumer group does not believe this claim. The consumer group tests this claim by surveying a random sample of 15 sports car owners who had the fuel injection system replaced. The ages of sports cars at the time of replacement were (in months) as follows:29, 42, 49, 48, 53, 46, 30, 51, 42, 52, 38, 47, 50, 34, 52Assume that that the age of sports cars at the time of replacement is normally distributed.Find the mean and sample standard deviation of the above data.Use this data to construct a 99 percent confidence interval for the mean number of months a fuel injection system lasts before it needs replacement. to monthsWe want to test the manufacturers claim that the fuel injection system lasts 48 months before it needs to be replaced.The null hypothesis used would be: The fuel injection system lasts on average less than 48 months.The fuel injection system…Of the total 161 patients with diabetes ketoacidosis (DKA), 13 had DKA before and after the pump therapy, 128 did not have DKA either before or after, 7 had DKA before but not after, and 13 did not have DKA before but after.
