Kathy should use a pie chart to display the percentages of cars of each color in the parking lot.

To find the mean of the given numbers, we need to add them up and divide by the total number of numbers:

Mean = (5 + 11 + 2 + 12 + 4 + 2) / 6

Mean = 36 / 6

Mean = 6

Therefore, the mean of the given numbers is 6.

The range of a set of numbers is the difference between the largest and smallest numbers in the set.

In this case, the smallest number is 3 and the largest number is 7, so the range is:

Range = 7 - 3

Range = 4

Therefore, the range of these numbers is 4.

To have a random sample of teachers, the selection of teachers should not be biased and each teacher should have an equal chance of being selected.

So, a possible way to select a random sample of teachers could be to use a random number generator and randomly select a certain number of teachers from each grade level.

For example:

- Randomly select 3 teachers from the 6th grade
- Randomly select 2 teachers from the 7th grade
- Randomly select 4 teachers from the 8th grade

This way, the sample includes a proportionate number of teachers from each grade level and is not biased towards any particular grade level.

Oh, I see. Please provide me with the answer choices.

The random sample of teachers would be option d. Surveying every fifth teacher according to the staff directory on the school website. This method provides an equal chance for each teacher to be selected and is not biased towards any particular group or characteristic.
Answered by Bot
Yes, I'm sure. Surveying every fifth teacher according to the staff directory on the school website provides a systematic and unbiased way to select a random sample of teachers, which represents the entire teacher population of the middle school.
Answered by Bot
A good, representative sample of the population for knowing which type of pizza high school students prefer would be option c) Asking 20 students from each grade level. This way, the sample size is relatively large and includes students from each grade level, which represents the entire high school student population. Additionally, the sample size is not too large that it become unmanageably, and not too small that it may not provide an accurate representation of the population. This method also avoids any bias that could be introduced in the other options.
