Question

based on the dot plot, which statements are correct? check all that apply.
eleven students answered mr. chius question.
twelve students answered mr. chius question.
three people studied for two hours.
three people studied for three hours.
everyone who responded studied for at least one hour.
four people studied for four or more hours.

Explanation:

Step1: Count total number of dots

Count all dots in the dot - plot. There are \(1 + 2+3 + 2+1+2+1=12\) dots.

Step2: Analyze each statement

• Statement 1: Eleven students answered. Since there are 12 dots (students), this is incorrect.
• Statement 2: Twelve students answered. As we counted 12 dots, this is correct.
• Statement 3: Three people studied for two hours. Count the dots above 2. There are 3 dots above 2, so this is correct.
• Statement 4: Three people studied for three hours. Count the dots above 3. There are 2 dots above 3, so this is incorrect.
• Statement 5: Everyone studied for at least one hour. There is a dot at 0, so this is incorrect.
• Statement 6: Four people studied for four or more hours. Count dots at 4, 5, 6. \(1 + 2+1 = 4\), so this is correct.

Answer:

B. Twelve students answered Mr. Chiu's question, C. Three people studied for two hours, F. Four people studied for four or more hours.
