QuestionLisetta's new temperature lowers the standard deviation. What can we conclude about today's temperature compared to the previous 10 days?

Studdy Solution

STEP 1

Assumptions1. Lisetta has a set of data showing the temperature at noon for10 consecutive days. . She adds today's temperature to the data set.
3. After adding today's temperature, the standard deviation of the data set falls.

STEP 2

The standard deviation is a measure of how spread out the numbers in a data set are. If the standard deviation falls, it means the numbers are becoming less spread out, or more closely clustered around the mean.

STEP 3

If today's temperature caused the standard deviation to fall, it must be closer to the mean of the previous10 days' temperatures than most of the other temperatures in the set.

STEP 4

Therefore, the conclusion that can be made is Today's temperature is close to the mean for the previous10 days.
