Final answer:
To calculate the minimum attendance for the year 2022 in cell B22, use the MIN function with the range that contains the relevant attendance data. Without the context of where the attendance data is located, it is not possible to select the correct answer from the provided options.
Step-by-step explanation:
The function that should be entered in cell B22 to calculate the minimum attendance for the year 2022 depends on the range which contains the attendance data for that year. Without further context, it is not possible to determine which of the provided options is correct. However, generally speaking, when using the MIN function in Excel to find the smallest number in a range, you should specify the exact range where the relevant data is. For example, if the attendance data for the year 2022 is indeed captured from cell B2 to B21, then the correct formula would be =MIN(B2:B21). It's important to not include B22 in your range if you are entering the formula in B22 itself to avoid a circular reference error.
