Question

which of the dot plots shows a skewed distribution? 3. create a dot plot showing a uniform distribution. 4. the data represent the number of ounces of water that 25 students drank before donating blood: 8, 8, 8, 16, 16, 16, 32, 32, 32, 32, 32, 32, 64, 64, 64, 64, 80, 80, 80, 80, 88, 88, 88. a. create a dot - plot for the data.

Explanation:

Step1: Recall skewed - distribution concept

A skewed - distribution has a long tail on one side. In a dot - plot, if the data points are not symmetrically distributed around a central value and cluster more on one side with a few values stretching out on the other side, it is skewed.

Step2: Analyze each dot - plot

• For the first dot - plot: The data points are somewhat symmetrically distributed around a central value range (around 1.2 - 1.8), so it is not skewed.
• For the second dot - plot: The data points are relatively evenly spread out with no clear long - tail, so it is not skewed.
• For the third dot - plot: The data points are symmetrically distributed around a central value range (around 12 - 16), so it is not skewed.
• For the fourth dot - plot: The data points cluster more on the left - hand side (around 1.2 - 1.4) and have a long tail stretching out to the right (1.6 - 2.1), indicating a right - skewed distribution.

Answer:

The fourth dot - plot shows a skewed distribution.
