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.
The 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.
