Question

The ages, in years, of 10 randomly selected passengers on a flight from Houston to New Orleans were recorded as follows:
{23, 48, 52, 34, 22, 53, 19, 23, 32, 27}
Calculate the sample mean age to the nearest integer.

A. 34 years
B.31 years
C. 33 years
D. 333 years

Answer 1

To calculate the sample mean age, we need to add up all the ages and then divide by the number of ages (which is 10).

The ages are: 23, 48, 52, 34, 22, 53, 19, 23, 32, 27.

First, we find the sum of these ages:

\[
23 + 48 + 52 + 34 + 22 + 53 + 19 + 23 + 32 + 27 = 362
\]

Now we divide the total sum by the number of ages (10):

\[
\text{Mean} = \frac{362}{10} = 36.2
\]

Rounding 36.2 to the nearest integer gives us 36.

None of the options provided match this result. However, based on the calculation, the answer is **36 years**. If you have further options or details, please provide them!
