Task $7$

$2\mathrm{.}2/3$ points

Calculate the number of

diamonds with a color rating of $D.$

$-0\mathrm{.}8$ The grader found the

following:

$-0\mathrm{.}5$ Only $4$ of the $7$

values in range M$13$:M$19$

are correct.

$-0\mathrm{.}3$ The formula in cell

M$13$ does not

appropriately reference

C$4$:C$354$ on the

DescriptiveStats

worksheet.

The formula I used for cell P$13$ is $=$COUNTIF$($C$4$:C$354,$L$13).$ Then I copied and pasted. Where did I go wrong?
