Question

the owner of a fruit stand gathered data for a week about the number of watermelons, pumpkins, and cantaloupes sold each day. she represented the data in two scatter - plots.
do either scatter plot indicate a positive correlation between the variables?
a. only plot a
b. only plot b
c. both plot a and plot b
d. neither plot a nor plot b

Explanation:

Step1: Recall positive - correlation concept

In a positive - correlation, as one variable increases, the other variable also increases.

Step2: Analyze Plot A

In Plot A, as the number of watermelons sold (x - axis) increases, the number of pumpkins sold (y - axis) also increases. So, Plot A shows a positive correlation.

Step3: Analyze Plot B

In Plot B, there is no clear pattern such that as the number of pumpkins sold (x - axis) increases, the number of cantaloupes sold (y - axis) consistently increases. There is no positive correlation in Plot B.

Answer:

A. only plot A
