EXCEL: Problem description (150 points)
Space… the final Excel frontier… at least for you this quarter ;o) Based on the input data given on the following worksheets and described below, fill out the remaining information as designated in the given problems. NOTE: On the worksheet are Q# hints to help you follow where the problems are being used to fill in the data.
SPACE This worksheet contains information pertaining to individual planets in our solar system. The following columns are considered input data: A thru E, G, I thru K, O and P. The goal here was to put a question directly after the input to which it pertains.
UNITS Here you will find conversions to aid in analyzing your data. Notice that most of this information are set conversions, however, due the learning nature of this exam, please be sure to use the cell references when using this data. Also, there is a named range specified for this worksheet called lightyear which is defined as units!$a$3. Be sure to use this named range when accessing this cell.
PROBLEMS
1. (8 pts) Write an Excel formula in cell space!G13 to determine how many planets have at least one moon.
2. (12 pts) Write an Excel formula in cell space!G14 to determine if only non-dwarf planets have moons. REMINDER: this type of problem is considered not updatable.
3. (16 pts) Write an Excel formula in cell space!F4, which can be copied down to space!F11, to determine the diameter size of ceres as compared to earth. To determine this value you use the diameter of ceres and divide that by the earth’s diameter. HINT: You cannot assume that the diameter of earth will always be in cell space!E6… you have to “look” for it ;o)
4. (20 pts) Write an Excel formula in cell space!H4, which can be copied down to space!H11, to determine how long in minutes it will take the sun’s rays to reach ceres. REMINDER: the data in column G designates millions of kilometers. NOTE: You will need to use the conversion factor(s) given on the units worksheets and don’t forget to use the named range.
5. (25 pts) Write an Excel formula in cell space!L4, which can be copied down to space!L11, to determine the orbit time in years for ceres rounded to the hundredths place. NOTE: Notice that the orbit time may be given in days, months or years according to column K.
6. (12 pts) Write an Excel formula in cell space!M4, which can be copied down to cell space!M11, to determine if ceres is a fun planet. A fun planet is one that either has more than two moons or has an orbit time in years greater than the average orbit time of all the planets.
7. (12 pts) Write an Excel formula in cell space!Q13 to determine the total number of moons that all the fun planets have together.
8. (10 pts) Write an Excel formula in cell space!N4, which can be copied down to cell space!N11, to determine the rank of the orbit time in years from smallest to largest for ceres.
9. (20 pts) Write an Excel formula in cell space!Q4, which can be copied down and across to cell space!R11, to determine the Celsius temperature conversion for the maximum temperature given in cell O4 for ceres. If the Celsius temperature is already given, then there is no need to change the resulting value, however, if the given type of temperature is Kelvin (as in cell P4) then a conversion is necessary FYI: the “c” in cell Q3 means that the values in this column should be Celsius temperatures and the “k” in cell R3 means that the values in this column should be Kelvin temperatures. NOTE: Cells Q2 and R2 are also considered input data and are values used for temperature conversions. In order to convert Celsius to Kelvin, you have to add 273.15 to the Celsius temperature; in order to convert Kelvin to Celsius, you have to subtract 273.15 from the Kelvin temperature.
10. (15 pts) You want to build a new lab with state of the art telescope equipment for viewing space. It’s going to cost $5,000,000 to build this new facility. Currently, there is an endowment of $1,000,000 that was given toward the cost of the new structure. An additional $15,000 per month will be donated for the next 10 years. Given an annual percentage rate of 10% compounded monthly, write an excel formula in cell space!Q14 to determine (true or false) if there will be enough money to pay for the building at the end of the 10 year period, if you invest the endowment today as well as the payments along the way.
ACCESS:
Problem description (150 points)
This
is an Access database setup to keep track of space shuttle missions. The
database consists of four tables that list the following:
Shuttle – This table lists
individual mission specifications including the trip location, the start date
of the mission, the number of days the mission will last, whether or not the
shuttle returned from its mission, and the base cost in millions of dollars for the mission. NOTE: The field called “return” is a yes/no
field, NOT a text field.
People – These are individual
astronaut costs associated with each mission. Astronauts need insurance for
each mission and they get hazard pay as well.
Equipment – These are
individual equipment costs associated with each mission.
Astronauts – Each record in this
table specifies the personal information about each astronaut in the shuttle
mission program. NOTE: The field called “married” is a yes/no field, NOT a text
field.
NOTE: Some missions do
not have any astronauts (unmanned flights); and some missions do not carry any extra
equipment. There are also some astronauts listed that have not yet been
assigned to a mission. These are not problems; they are just part of the logic
of the problem (i.e. not all primary key values are given in the foreign key
field).
Portions of each table in this database are shown at
the end of this exam. Assume any
referential data integrity errors are corrected prior to writing the queries.
1.(16
pts) Determine the primary and foreign key(s) for each table (if any) and draw
lines indicating the relationships between the tables.
SHUTTLE
table Primary Key: Foreign Key(s): PEOPLE table Primary Key: Foreign Key(s): EQUIPMENT
table Primary Key: Foreign Key(s): ASTRONAUT
table Primary Key: Foreign Key(s):
2.
(12 pts) Is it okay to join the SHUTTLE and EQUIPMENT tables in one query,
called Q2A, then write a second query, called Q2B, to join Q2A with the PEOPLE
table (yes or no)? Explain.
3.
(15 pts) Write an Access query that lists the mission number and location for
shuttle missions which either:
* started the mission in the month of May
2008 and stayed in space for more than 20 days
OR
* visited the moon
