Explanation:

Step1: Count data in intervals

Count how many numbers from the data - set fall into each interval.
For the interval \(0 - 9\), the number \(5\) and \(7\) are in this range, so the frequency is \(2\).
For the interval \(10 - 19\), the numbers \(12\), \(14\), \(18\), \(19\) are in this range, so the frequency is \(4\).
For the interval \(20 - 29\), the numbers \(21\), \(23\), \(26\), \(28\), \(28\) are in this range, so the frequency is \(5\).
For the interval \(30 - 39\), the numbers \(31\), \(33\), \(34\), \(36\) are in this range, so the frequency is \(4\).
For the interval \(40 - 49\), the numbers \(40\), \(41\), \(43\), \(44\), \(46\), \(48\), \(48\), \(49\) are in this range, so the frequency is \(8\).
For the interval \(50 - 59\), the numbers \(50\), \(56\), \(57\), \(58\) are in this range, so the frequency is \(4\).

Answer:

Interval	Frequency
\(10 - 19\)	\(4\)
\(20 - 29\)	\(5\)
\(30 - 39\)	\(4\)
\(40 - 49\)	\(8\)
\(50 - 59\)	\(4\)
