how many shipments had at least 19 boxes but fewer than 76 boxes? shipments

Explanation:

Step1: Identify relevant data

We need data from 19 (inclusive) to 76 (exclusive).

Step2: Count values

For stem - 1, values 19 and above are considered. From stem 1, there are 4 values (19 is not included in 1 - row values here as we start from 19, but values like 19+ are counted). For stem 2 - 6, all values in those rows are relevant. Stem 2 has 0 values, stem 3 has 0 values, stem 4 has 1 value, stem 5 has 5 values, stem 6 has 1 value. Stem 7 values above 76 are not counted, so stem 7 has 1 value (73).

Step3: Sum up

Sum of relevant values: \(4 + 0+0 + 1+5 + 1+1=12\)

Answer:

12
