*click the tally box to count up. the minus counts down.
interval tally frequency
0 - 9
10 - 19
20 - 29
30 - 39
40 - 49

Explanation:

Step1: Count numbers in \(0 - 9\)

Numbers in \(0 - 9\) are \(9,4\). So frequency is \(2\).

Step2: Count numbers in \(10 - 19\)

Numbers in \(10 - 19\) are \(18,12,11,10,19,18,15\). So frequency is \(7\).

Step3: Count numbers in \(20 - 29\)

Numbers in \(20 - 29\) are \(27,27,27,23,23,26\). So frequency is \(6\).

Step4: Count numbers in \(30 - 39\)

Numbers in \(30 - 39\) are \(30,39,36,30,32,38\). So frequency is \(6\).

Step5: Count numbers in \(40 - 49\)

Numbers in \(40 - 49\) is \(40\). So frequency is \(1\).

Answer:

\(0 - 9\): \(2\); \(10 - 19\): \(7\); \(20 - 29\): \(6\); \(30 - 39\): \(6\); \(40 - 49\): \(1\)
