The heights of 1000 students at a local school were recorded and found to be approximated by the normal curve below. Which answe
Vlada [557]

Answer:

The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.

Step-by-step explanation:

The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.

For a normal curve, the mean, median and mode are the same and represents the center of the distribution.

The center of the normal curve below is at the height 63 inches.

Thus, the mean of the distribution of heights of students at a local school is 63 inches.

The standard deviation represents the spread or dispersion of the data.

From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.

So, the standard deviation is 4 inches.

Vikki [24]
<h2>Answer:</h2>

The method suggested by Bobby is better than Allie.

<h2>Step-by-step explanation:</h2>

A fair sample is a sample where each sample has an equal opportunity to get selected for any survey.

Here, in the given question, Allie suggested that the first 3 students to arrive in class the next day should be the representatives. This sample is not random or fair.

Whereas, Bobby suggested that each student roll 2 numbers cubes and the 3 students with the highest sum should be the representatives. This method is a fair method.

The method suggested by Bobby is better than Allie as every student will get an equal chance to perform and also has an equal chance to win and get a high sum.
