Question

for making a scatter plot of the data set, which would be the best scale and interval for the axis that represents the number of girls?
boys\t12\t24\t7\t5\t11\t37\t18
girls\t3\t13\t6\t6\t10\t7\t11
a. 0 to 15 with intervals of 1
b. 0 to 15 with intervals of 5
c. 0 to 40 with intervals of 1
d. 0 to 40 with intervals of 5
step 1. look at the numbers for the axis you want
step 2. find the smallest number
step 3. find the largest number
step 4. compare the scale in the answers to your smallest and largest numbers
step 5. look at the interval in the answers and make sure you can count by the given interval in the table

Explanation:

Step1: Identify girls' data

Girls' data: 3, 13, 6, 6, 10, 7, 11.

Step2: Find min and max

Smallest number: \( 3 \), Largest number: \( 13 \).

Step3: Analyze scale options

Scale should cover 3 - 13. Option C (0 - 40) and D (0 - 40) are too large. Between A (0 - 15, interval 1) and B (0 - 15, interval 5).

Step4: Check interval feasibility

Data has values like 3, 6, 7, 10, 11, 13. Interval of 1 allows precise plotting (e.g., 3, 6, 7, 10, 11, 13 are distinct and fit 0 - 15). Interval of 5 would group values (e.g., 3,6,7 in 0 - 5, 5 - 10, 5 - 10), less precise. So A is better.

Answer:

A. 0 to 15 with intervals of 1
