Answer:

Step-by-Step Analysis

Which category had the greatest frequency?

How many students spelled 35 to 39 words correctly?

What percent of the 200 students who took this test spelled 35 to 39 words correctly?

(a) Greatest Frequency

From the histogram data:

Each bar represents the number of students in different ranges of words spelled correctly.

We need to identify which bar has the highest count.

Assuming the highest count is visually indicated on the histogram, identify the category with the tallest bar. If the histogram shows "22" as the highest value, it indicates that the category with the highest frequency is the one corresponding to this count.

(b) Number of Students who Spelled 35 to 39 Words Correctly

The number of students who spelled 35 to 39 words correctly can be directly read from the histogram. Assuming the histogram value for the category 35-39 is given as 22:

22 students spelled 35 to 39 words correctly.

(c) Percentage of Students who Spelled 35 to 39 Words Correctly

To find the percentage:

Identify the total number of students: 200.

Identify the number of students in the 35-39 range: 22.

Use the formula for percentage

Thus, 11% of the students spelled 35 to 39 words correctly.

Summary of Answers

Category with the Greatest Frequency: The category corresponding to the tallest bar on the histogram (assumed to be visually checked).

Number of Students who Spelled 35 to 39 Words Correctly: 22 students.

Percentage of Students who Spelled 35 to 39 Words Correctly: 11%.
