Explanation:

Step1: Count data per class interval

Data: 77,73,81,86,90,87,80,82,96,88,75,67

• 50-59: 0 values
• 60-69: 1 value (67)
• 70-79: 3 values (77,73,75)
• 80-89: 5 values (81,86,87,80,82,88? Correction: 81,86,87,80,82,88 is 6? Wait original data count: 12 values. Let's recount:

60-69: 67 (1)
70-79:77,73,75 (3)
80-89:81,86,87,80,82,88 (6)
90-100:90,96 (2)
Histogram shows 50-59:1, 60-69:0, which contradicts (no data in 50-59, 1 data in 60-69).

Step2: Check option alignment

Option 1 says "not correct because no data in 50-59" – matches the error (histogram has 1 in 50-59 but actual data has 0 there).

Answer:

It is not correct because there was no data in the class 50-59.
