- No.
Step-by-step explanation:
The foot lengths in inches for 11 randomly selected people taken in 1988. are
First, we need to arrange the given data in ascending order.
1. To find the range<u>,</u> we need to determine the maximum value and the minimum value in the given sample, and to subtract them. The maximum value is 9.7 and the minimum value is 8.5. Therefore,
The variance is given by
where
In this case, . Therefore,
Hence, the variance is
Now, we can calculate the standard deviation.
2. No, this statistics are not representative of the current population of all people, since they are measured for the 1988. population.
Answer:
