Question

what is the class width for a frequency distribution with 7 classes?
the class width is 7.
part: 1 / 5
part 2 of 5
find the class limits. the first lower class limit is 60.
class limits
60-

Explanation:

Step1: Determine the upper limit of the first class

Since the class width is \(7\) and the lower limit of the first class is \(60\), the upper limit of the first class is \(60 + 7-1=66\).

Step2: Determine the lower limit of the second class

The lower limit of the second class is \(60 + 7 = 67\), and the upper limit is \(67+7 - 1=73\).

Step3: Determine the lower limit of the third class

The lower limit of the third class is \(67+7=74\), and the upper limit is \(74 + 7-1 = 80\).

Step4: Determine the lower limit of the fourth class

The lower limit of the fourth class is \(74+7 = 81\), and the upper limit is \(81+7 - 1=87\).

Step5: Determine the lower limit of the fifth class

The lower limit of the fifth class is \(81+7=88\), and the upper limit is \(88 + 7-1=94\).

Step6: Determine the lower limit of the sixth class

The lower limit of the sixth class is \(88+7 = 95\), and the upper limit is \(95+7 - 1 = 101\).

Step7: Determine the lower limit of the seventh class

The lower limit of the seventh class is \(95+7=102\), and the upper limit is \(102+7 - 1=108\).

Answer:

The class limits are:
\(60 - 66\)
\(67 - 73\)
\(74 - 80\)
\(81 - 87\)
\(88 - 94\)
\(95 - 101\)
\(102 - 108\)
