Question

the line plot shows the ages at which a group of musicians started to play an instrument. based on the data in the line plot, which statement is not true? fewer of the musicians started to play at age 12 than at age 5. the range of the ages shown is 8 years. most of the musicians started to play at age 9 or older. there are 34 musicians included in the data.

Explanation:

Step1: Count number of 'x's at age 12 and 5

At age 12, there are 2 'x's. At age 5, there are 3 'x's. So, fewer musicians started at age 12 than at age 5. This statement is true.

Step2: Calculate the range

The highest age is 12 and the lowest is 4. Range = 12 - 4 = 8 years. This statement is true.

Step3: Count number of 'x's at age 9 or older

At age 9, there are 5 'x's, at age 10 there are 4 'x's, at age 11 there are 3 'x's and at age 12 there are 2 'x's. Total = 5 + 4+3 + 2=14. There are 34 total 'x's. So, most musicians did not start at age 9 or older. This statement is not true.

Step4: Count total number of 'x's

Counting all 'x's: 2+3 + 4+5+5+4+3+2 = 28, not 34. This statement is not true. But we only need one non - true statement.

Answer:

Most of the musicians started to play at age 9 or older.
