The U.S. Department of Agriculture reports that the mean cost of raising a child from birth to age 2 in a rural area is $9405. You believe this value is incorrect, so you select a random sample of 900 children (age 2) and find that the mean cost is $9290 with a standard deviation of $1540. At a= 0.05, is there enough evidence to conclude that the mean cost is different from $9405? List the steps involved in hypothesis testing using: a) the traditional/classical method; b) the probability-value method. Provide an example of each. Choose a variable (such as number of daily admissions at a local theater or number of miles students have to commute daily to get to their college.) Before collecting the data, decide what a likely average might be, then complete the following: a.Write a brief statement of purpose of the study b.Define the population c.State the hypotheses for the study d.Select an a value e.State how the sample was selected f.Show the raw data g.Compute the test statistic h.Find the critical values(s) i.State the decision j.Summarize the results
