W3: Topic – Encryption and Lab 3

I appreciate your participation in this discussion. For this assignment, create an original post addressing the topic below prior to midnight ET on Wednesday. Continue to follow your classmates’ posts for the remainder of the week and post at least two follow-up messages to your professor’s or classmates’ posts prior to midnight ET on Sunday. Your follow-up posts can add additional insight to a classmate’s opinions or can challenge their opinions. Use examples from your experiences, readings, or from your own research, to support your views, as appropriate. Be sure to read the follow-up posts to your own posts and reply to any questions or requests for clarification.  Thanks!

Instructions:

1. Discuss the role of encryption in ensuring confidentiality; use a popular encryption to make your point if needed.
2. List any observations, tips or questions about this lab that would prove helpful to fellow students prior to midnight on Wednesday and comment on other student posts with value added comments (not simply agreeing) by midnight Sunday for full credit consideration.

San Diego Sailing keeps data about its fleet of rental and charter boats. One of the sheets is missing a piece of data and another sheet has circular reference errors. You will complete work on these sheets, calculate projected rates for each boat, and build basic statistics about past rentals.

[Student Learning Outcomes 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7]

File Needed: SanDiegoSailing-02.xlsx (Available from the Start File link.)

Completed Project File Name: [your name]-SanDiegoSailing-02.xlsx

Skills Covered in This Project

• Create and copy formulas.
• Use formula auditing tools.
• Set mathematical order of operations.
• Use relative, mixed, and 3D cell references.
• Use COUNTIF and SUMIF functions.
• Build an IF formula.
• Insert the TODAY function.

NOTE: If group titles are not visible on your Ribbon in Excel for Mac, click the Excel menu and select Preferences to open the Excel Preferences dialog box. Click the View button and check the Group Titles check box under In Ribbon, Show. Close the Excel Preferences dialog box.

1. Open the SanDiegoSailing-02.xlsx workbook.
2. If the workbook opens in Protected View, click the Enable Editing button so you can modify it.
3. The file will be renamed automatically to include your name. Change the project file name if directed to do so by your instructor, and save it.
4. Review a formula.
   1. Click the New Prices sheet tab and review the Formula bar.
   2. Click cell D5. The formula begins with 1+D4.
5. Edit and copy a formula with mixed references.
   1. Edit the formula in cell D5 to show D$4 instead of “D4.” The formula should multiply one plus the percentage value in cell D4 by the current rate on the Fleet sheet ($H5). With an absolute reference to row 4 and column H on the Fleet sheet, you can copy the formula down the column (Figure 2-105).Figure 2-105 Mixed reference in the edited formula
   2. Copy the formula in cell D5 to cells D6:D19 without formatting to preserve the border.
   3. Select cells D5:D19 and drag the Fill pointer to copy the formulas to cells E5:E19.
   4. Click cell E6. The formula is adjusted to use the percentage value in cell E4 in place of cell D4. Note also that the reference on the Fleet sheet ($H6) is adjusted to show the correct row.
6. Build a formula with mixed references.
   1. Click cell F5 and type =(1+ to start the formula.
   2. Select cell F4 and make it an absolute reference to the row but not the column.
   3. Type )* for the closing parenthesis and multiplication.
   4. Click cell I5 on the Fleet sheet, and make the reference absolute for the column but not the row (Figure 2-106).Figure 2-106 Mixed references in the new formula
   5. Copy the formula down column F without formatting to preserve the border.
   6. Format cells F5:F19 as Currency and then copy cells F5:F19 to cells G5:G19.
7. Build an IF function formula.
   1. Click the Fleet sheet tab and select cell G5. Rental boats with a stove in the galley must seat 8 or more people.
   2. Create an IF function in which the logical_test argument determines if there are 8 or more seats.
   3. Use Yes for the value_if_true argument. Use No for the value_if_false argument. (If you type the formula, enclose the text arguments within quotation marks.)
   4. Copy the formula to cells G6:G19 without formatting and then center the data in column G.
8. Insert the TODAY function in cell B21. Format the date to show the month spelled out, the date, and four digits for the year (January 1, 2020).
9. Create a division formula.
   1. Click the Bookings sheet tab and select cell F5. Calculate average revenue per passenger by dividing the fee by the number of passengers.
   2. Build the division formula.
   3. Copy the formula in cell F5 to cells F6:F19.

    5. Copy the formula in cell D27 to cells D28:D30.
    6. Edit the criteria in each copied formula in cells D28:D30 to reflect the boat make.
11. Create and copy a SUMIF function to calculate total revenue by boat make.
    1. Select cell E27.
    2. Start the SUMIF function with cells $C$5:$C$19 as the Range.
    3. Set the Criteria argument to ben*.
    4. Set the Sum_range argument to cells $E$5:$E$19.
    5. Copy the formula in cell E27 to cells E28:E30.
    6. Edit the criteria in each copied formula in cells E28:E30 as needed.
12. Complete formatting.
    1. Apply the Currency format to all values that represent money.
    2. Format the labels in cells A1:A2 as 18 point.
    3. Select cells A1:F2 and click the Alignment launcher [Home tab, Alignment group]. Center the labels across the selection.

    6. Select cells A4:F19 and apply All Borders. Do the same for cells C25:E30.
    7. Center the page horizontally.
13. Save and close the workbook (Figure 2-107).Figure 2-107 Excel 2-5 completed
14. Upload and save your project file.
