Solution Steps

Step 1: Identify the Variables
  • The problem requires us to draw a scatter diagram with MRI count as the explanatory variable (x-axis) and IQ as the response variable (y-axis).
Step 2: Analyze the Data
  • The data provided includes MRI counts and IQ scores for 5 females and 5 males.
  • We need to plot MRI counts on the x-axis and IQ scores on the y-axis.
Step 3: Choose the Correct Scatter Diagram
  • Examine the given scatter diagrams (A, B, C, D) to determine which one correctly plots MRI counts on the x-axis and IQ scores on the y-axis.

Final Answer

  • The correct scatter diagram is B. This diagram correctly places MRI counts on the x-axis and IQ scores on the y-axis.
