Suppose there are 10 five and six-year-old attending a birthday party. When a 30 year old mother walks into the room with an infant in her arms, what happens to the mean age in the room? what happens to the standard deviation of ages in the room?

A. The mean and standard deviation of both change.
B. The meaning will change, but the standard deviation will stay approximately the same.
C. I mean will stay approximately the same, but the standard deviation will change.
D. The mean and standard deviation will both stay approximately the same.

The mean of a dataset exists as the sum of all values divided by the total number of values. It's the most generally utilized measure of central tendency and exists often referred to as the “average.”

The median exists as the middle value in a list ordered from smallest to largest. The mode exists as the most frequently occurring value on the list.

The standard deviation exists as a statistic that measures the dispersion of a dataset relative to its mean and is computed as the square root of the variance. The standard deviation exists estimated as the square root of variance by determining each data point's deviation relative to the mean.

Standard deviation describes how spread out the data is. It is a measure of how far each observed value exists from the mean.

Here given that,

There are 10 five and six-year-olds attending a birthday party.
When a 30-year-old mother walks into the room with an infant in her arms.
what happens to the mean and standard deviation of ages in the room.

Hence, A. The mean and standard deviation of both change.
