The average temperature this time of year is 67o with a standard deviation of 5o.
What is the corresponding z-score for a temperature of 63o?
Is 63o within the typical range for this time of year?
(ie., is it within 1 SD from the Mean?)
What if the temperature was 78o tomorrow? Is this temperature still within the normal range for the year (within 95%)? Why/Why not?
The average temperature this time of year is = 67o with a standard deviation of = 5o.
What is the corresponding z-score for a temperature of x = 63o?
Is 63o within the typical range for this time of year?
As we can see that -1 < z-score < 1 63o is within the typical range for this time of year.
(ie., is it within 1 SD from the Mean?)
What if the temperature was x = 78o tomorrow? Is this temperature still within the normal range for the year (within 95%)? Why/Why not?
z-score =
Since this is not within 1 SD of the mean, we can that this temp is not within the normal range.
