Question

step 1 so far our calculations have indicated a class width of 15.29. however, to ensure the classes cover all the data, we must increase the calculated result to the next whole number. rounding 15.29 up to the nearest whole number gives us blank. therefore, the class width is blank.

Explanation:

Step1: Understand Rounding Up

When rounding up 15.29 to the nearest whole number, we look at the decimal part. Since we need to round up (increase to the next whole number), we ignore the decimal and add 1 to the whole number part.

Step2: Perform Rounding

The whole number part of 15.29 is 15. Adding 1 gives \( 15 + 1 = 16 \).

Answer:

Rounding 15.29 up to the nearest whole number gives us \(\boldsymbol{16}\). Therefore, the class width is \(\boldsymbol{16}\).
