8. To be a Bunk Leader, a staff member must have over 4 service years and have completed leadership training. In cell L2, enter
Nitella [24]

Answer:

=IF(AND([Service Year]>4,[Leadership Training]="Yes"),"Yes","No")

Explanation:

To make use of structured references, a table has to be defined (created). Assume that the table definition is as follows;

Staff --- Service Year --- Leadership Training --- Status

In cell L2, type the above formula

Analyzing the formula:

=; An Excel formula must start with an = sign

IF; This signifies  that the formula is an "IF" function

AND; This signifies that there are more than one condition in thee formula and all conditions must be true

[Service Year]>4; The question requires that the formula uses a structured referencing. Structured referencing is such that the columns of a table are called instead of cell names;

Here, reference is being made to [Service Year] because Service Year is a column name and its value must be greater than 4

[Leadership Training]="Yes"; The above analysis is applicable here too because Leadership Training is column name and it must be "Yes" for it to return a true value.

"Yes"; Return Yes if both conditions are true

"No"; Otherwise, return No.
