Question

plot the points
how many hours did you read last
week?
sammi made a mistake in step 1 because his number line did not include all numbers in the data set.
sammi made a mistake in step 2 because he chose a title without knowing if the table represents the number of
hours read per week.
sammi made a mistake in step 3 because he did not correctly plot each dot above the appropriate place on the
number line.
sammi did not make a mistake.

Explanation:

Step1: Analyze the number line

The number line in the plot has values \(3\), \(4\), \(5\), \(6\). If the data set only has values within this range (as per the context of the dot - plot), then the number line is appropriate.

Step2: Analyze the title

The title “How Many Hours Did You Read Last Week?” is a reasonable title for a dot - plot that is showing the number of hours read (assuming the data is about hours of reading in a week).

Step3: Analyze the dot - plotting

Each dot is placed above the appropriate number on the number line. For example, the dots above \(3\) are correctly placed, the dots above \(4\) are correctly placed, the dots above \(5\) are correctly placed, and the dots above \(6\) are correctly placed.

Answer:

Sammi did not make a mistake.
