Answer:
Mean is the measure of central tendency is most appropriate to describe the given data.
Step-by-step explanation:
We are given the following in the question:
The distribution of time in seconds is a bell shaped distribution that is a normal distribution.
Properties of a normal distribution:
- The mean, mode and median for a normal distribution are equal.
- The mean divides the data into two equal parts.
- The area under the graph is 1.
- Thus, mean is the most appropriate measure of central tendency for normally distributed data.
Thus, the correct answer is
Mean is the measure of central tendency is most appropriate to describe the given data.

Answer:
80.88
Step-by-step explanation:
The mean is the average of the numbers. To calculate that, just add up all the numbers, and then divide by how many numbers there are. In other words it is the sum divided by the count.
95 + 45 + 37 .....
divided by 24 (the total number of numbers)
1,941 / 24 = 80.875
80.8<u>7</u>5 rounded to the nearest hundredth = 80.88
*
(hundredths place)
Rounding rule: If the digit to the right of the place you are rounding to is 5 or more, then round up to the next digit.
