Answer:
The <em>z</em>-score for a a class with 21 students is <u>-1.33</u>.
Step-by-step explanation:
The <em>z</em>-score of a raw <em>X</em> is computed by subtracting the mean of a distribution from the raw score <em>X</em> and dividing the result by the standard deviation of the distribution.
The <em>z</em>-scores are standardized scores and follow a Standard normal distribution.
Given:
μ = 38.1
σ = 12.9
<em>X</em> = 21
Compute the <em>z</em>-score for the raw score <em>X</em> as follows:
Thus, the <em>z</em>-score for a a class with 21 students is <u>-1.33</u>.
Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.
Step-by-step explanation:
A line plot is a graph that shows frequency of data along a number line. It is best to use a line plot when comparing fewer than 25 numbers. It is a quick, simple way to organize data.
The main difference between a line plot and a line graph is that the line plot shows the frequency of number within a set, and the line graph shows the value of one variable relative to another.The number of dots in a line plot will be equal to the number of data points.
Hence, there are 12 pieces of data in the given line lot, so there will be 12 dots.
