choose the correct histogram below

a.
b.

c.

d.

Explanation:

Step1: Analyze Class Frequencies

We have class frequencies: Class A (1), B (3), C (8), D (8), E (8), F (1), G (2).

Step2: Match with Histogram Options

• Option A: The frequencies for the classes (from left - right: A - G) match the given frequencies (1, 3, 8, 8, 8, 1, 2).
• Option B: The frequencies do not match as the initial classes (A - B) have incorrect bar heights compared to the given frequencies.
• Option C: The frequencies are not in line with the given data (the pattern of frequencies is different).
• Option D: The frequencies are not in accordance with the given class - frequency distribution.

Answer:

A.
