Use the information in the table to complete the dot plot.
The number missing on the number line is $\square$. There should be $\square$ dots above the number 4. There should be $\square$ dots above the number 6. A good title for the dot plot is $\square$
Answer (1)
The missing number on the number line is 5. There should be 2 dots above the number 4. There should be 3 dots above the number 6. A good title for the dot plot is 'Age at Which First Tooth Was Lost'.
Explanation
Understand the problem We are given a table that shows the ages at which people lost their first tooth and the corresponding tally. We need to complete the dot plot using this information.
Identify the missing number The number line should include all the ages listed in the table, which are 4, 5, 6, and 7. The missing number on the number line is 5.
Determine dots above 4 The tally for age 4 is 2, so there should be 2 dots above the number 4.
Determine dots above 6 The tally for age 6 is 3, so there should be 3 dots above the number 6.
Suggest a title A good title for the dot plot would be something related to the age at which people lost their first tooth. A suitable title is 'Age at Which First Tooth Was Lost'.
Examples
Understanding the distribution of ages when children lose their first tooth can help pediatric dentists anticipate and prepare for common dental milestones. For example, if a dentist sees a large number of children around age 6 losing their first tooth, they can plan educational programs for parents about proper dental care during this period. This type of data analysis is crucial in public health for planning and implementing targeted interventions.
