C268 questions and answers 2026\2027 A+ Grade


In the "Input Analysis" section of the spreadsheet model, calculate the average attendance and sales for
each type of product from the past events listed in the "Past Events" worksheet.
- correct answer =AVERAGE('Past Events'!C4:C103) for each column



In the "Input Analysis" section of the spreadsheet model, calculate the sample standard deviation for
attendance and sales for each type of product from the past events listed on the "Past Events"
worksheet. (Note for Excel 2007 users: Excel 2007 does not support a specific function to calculate
sample standard deviations. Use the STDEV function instead.)
- correct answer =STDEV.S('Past Events'!C4:C103) for each column



In the "Input Analysis" section of the spreadsheet model, calculate the 95% confidence interval for the
sales for each type of product. (You will not calculate a confidence interval for attendance.) Use the
number of events (calculated in cell I3) as part of your calculations. (Note to Excel 2007 users: the
CONFIDENCE.NORM function is not supported in Excel 2007. Use the CONFIDENCE function instead.)
- correct answer =CONFIDENCE.NORM(0.05,J7,$I$3)



In the "Input Analysis" section of the spreadsheet model, calculate the correlations between the sales of
each type of product and event attendance. Use appropriate ranges from the "Past Event" worksheet
for your calculations.
- correct answer =CORREL('Past Events'!$C$4:$C$103,'Past Events'!D4:D103)



The sales for which product type are most highly correlated with attendance? Select the correct answer
from the drop-down list in cell L32.
- correct answer Food (highest correlation number)



In the "Input Analysis" section of the spreadsheet model, calculate a sales forecast for each type of
product if expected attendance at the future event is 18000 people. Reference cell I13 (the attendance
forecast) for your calculations.
- correct answer =FORECAST($I$13,'Past Events'!D4:D103,'Past Events'!$C$4:$C$103)

, In the "Input Analysis" section of the spreadsheet model, calculate the upper limit for your sales forecast
for each type of product if expected attendance at the future event is 18000 people. Reference the
confidence interval you created for your calculation.
- correct answer =I16+J8

(sales forecast + 95% confidence interval)



In the "Input Analysis" section of the spreadsheet model, calculate the lower limit for your sales forecast
for each type of product if expected attendance at the future event is 18000 people. Reference the
confidence interval you created for your calculation.
- correct answer =I16-J8

(sales forecast - 95% confidence interval)



How likely is it that food sales would exceed $220,000 if attendance is 18,000 people? Select the correct
answer from the drop-down list in cell L35.
- correct answer <5% chance



In the "Event Profitability Analysis" section of the model, enter the projected sales for each product type
for this event by referencing your sales forecast from the "Input Analysis" section of the model.
- correct answer =I16 (calculated previously)



Calculate the cost of goods sold (COGS) for each product. The COGS is calculated as the sales for each
product type times the COGS percentage from the "Model Inputs" section of the model for that product
type.
- correct answer =C15*C4 (gross profit * COGS %)



Calculate the gross profit for each product. The gross profit is calculated as the sales minus the COGS for
each product.
- correct answer =C15-C16



Which product generates the largest gross profit? Select the correct answer from the drop-down list in
cell L38.
- correct answer Merchandise (line 17)



Calculate the commissions paid for each product type. The commissions paid are calculated as the
expected sales for each product type times the commission percentage from the "Model Inputs" section
