A town official claims that the average vehicle in their area sells for more than the 40th percentile of your data set. Using the data, you obtained in week 1, as well as the summary statistics you found for the original data set (excluding the super car outlier), run a hypothesis test to determine if the claim can be supported. Make sure you state all the important values, so your fellow classmates can use them to run a hypothesis test as well. Use alpha = .05 to test your claim. (Note: You will want to use the function =PERCENTILE.INC in Excel to find the 40th percentile of your data set) First determine if you are using a z or t-test and explain why. Then conduct a four-step hypothesis test including a sentence at the end justifying the support or lack of support for the claim and why you made that choice

A Realtor claims that no more than half of the homes he sells are sold for less than the asking price. When reviewing a random sample of 16 sales over the past year, he found that actually 13 were sold below the asking price. (a) The assumption of normality is justified.
