The data set shows the high temperatures during a week in August.
Sunday Monday Tuesday Wednesday Thursday Friday Saturday
103 101 99 100 89 99 98
When calculating the average high temperature for the week, Mrs. Ortiz said that Thursday's data should be excluded because a cold front moved through that day.
Evaluate this claim by selecting the statement that best reflects why the reasoning is either correct or flawed.

Best ResponseYou've already chosen the best response.0The reasoning is flawed. Even though Thursday's temperature is an outlier, it occurred during that week and there is no reason to exclude it. The reasoning is flawed. Thursday's temperature is not an outlier. The reasoning is correct. Thursday's temperature is an outlier, and excluding it will lower the mean. The reasoning is correct. Thursday's temperature is not an outlier, but it should be excluded because it was the coolest day of the week.

Best ResponseYou've already chosen the best response.0I'm not sure why you would exclude data just because it is an outlier though.

Best ResponseYou've already chosen the best response.0you definitely don't throw away data, unless you know it is bogus (the thermometer was broken, for example).

Best ResponseYou've already chosen the best response.0An outlier is a number that is "far" from the average. 89 looks "far" from the average of the other numbers.... but it does not matter... we keep it.
