Questions 5-10 are based on the Excel file "Minitest4DataQ5through10.xlsx".

In auditing you can ask two managers at an audit company about the chance one of the particular borrowers will default on their loan and get two very different forecasts of the probability of default. This audit situation analogizes nicely to a more everyday life situation: Will it rain or not rain?

Ted and Yoon Ju differ on who the better local weather meteorologist is. Ted swears by the weather forecast at the local ABC TV channel. Yoon Ju thinks more accurate weather forecasts can be had by tuning into the local NBC TV channel. They agree it would help to look at actual data to see who is right. So, they look at the month of April.

Ted says, it actually rained twelve days during the month and that the two meteorologists are equally accurate because their average forecast is a 50% probability of rain across the 30 days. That means they each expected it to rain 15 days, as 50% of 30 is 15. So each made us take an umbrella on 3 days too many, 15 minus 12. He also says that the meteorologist at ABC more helpful because it's better to take your umbrella to work when you do not really need it. "Forewarned is forearmed!" he says. Yoon Ju counters that it's more important in her book to not cancel outdoor activities needlessly, saying, "Overall, they're equally accurate and leave it at that."

Q5. Which meteorologist is more accurate on rainy days?

(Hint: I recommend that you download the file and familiarize yourself with it. You will be doing some computations and such with the data! You also likely would benefit if you converted the "Did it Rain?" column of "yes" and "no" into a new column of 1's and 0's.)
