$1.$ Lael Masterson works in the Student Activities Office at Valerian State College in Illinois. Lael has started compiling information on students who are interested in helping run student organizations at Valerian State, and she needs your help completing the workbook.

Switch to the Student Representatives worksheet. In cell E$2,$ enter a formula using the HLOOKUP function as follows to determine a student's potential base hourly rate $($which is based on the number of years of post$-$secondary education$)$:

a$.$ Use a structured reference to look up the value in the Post$-$Secondary Years column. Retrieve the value in the $2$nd row of the table in the range P$13$:U$14,$ using an absolute reference. Because base hourly rate is tiered based on the number of years of education, find an approximate match.

b$.$ Fill the formula into the range E$3$:E$31,$ if necessary.

$2.$ Student organizations sometimes require transportation for off$-$campus activities, and school policy requires students to be over $23$ years old to serve as transport.

Lael wants to determine how many of the active students will be eligible to transport other group members. In cell J$2,$ enter a formula using the IF function and structured references as follows to determine if Kay Colbert can serve as authorized transport:

a$.$ The function should use a reference to the value in the Age column to determine if the student's age is greater than $23,$ and should return the text Yes if true and No if false.

b$.$ Fill the formula into the range J$3$:J$31,$ if necessary. show the calculation
