The syntax of which of the following formulas would allow the analyst to count purchase sizes of two or more?

Correct
The COUNTIF formula =COUNTIF(H2:H30, “>=2”) has a condition that would allow the analyst to count all purchase size values in Column H that are two or more. The condition is greater than or equal to 2 (“>=2”), so this calculation would return a count of “8” because there are 8 values in Column H that are greater than or equal to 2.
