1. Design an Input dialog box window which accepts the last year from a drop down menu:

Year 2017 2016 2015

For example, if the last year selected is 2017, the SD will be calculated from 2008 to 2017.

MEDIUM. The output message will be Warning Sale Growth.

? If the SD is greater than or equal 58.90, this indicates that the growing of the market is FAST. The output message will be Healthy Sale Growth.

4. Give your answer formatted to two decimal ex: 99.99.

In this assignment you have to write a program in JAVA to create the Standard Deviation (SD) of the sales for the past 10 years. The standard deviation gives the sales manager a full idea of how the market changed in the past 10 years.

Your JAVA program will compute SD according to the formula below:

The standard deviation formula:

Where X is the sale in a specific year (must be a random value in the range 600 - 800). N is the number of years in this case N = 10. S: is the standard deviation that must be calculated, you may change the name to SD. Use a loop to read 10 random sales values for the 10 years.

Your JAVA program must check the calculated Standard deviation (SD) value according to the following criteria:

? If the SD less than or equal 50.90, this indicates that the growing of the market is SLOW. The output message will be Dangerous Sale Growth.

? If the SD is in the range 50.90 and 58.90 (exclusive), this indicates that the growing of the market is

5. The output must be in the form of a dialog box window as shown below. For example, if the SD less than or equal 50.90, the output should look like (all in one dialog box window):

Year is: 2017 The sale standard deviation is 50.73 The growing of the market is SLOW Dangerous Sale Growth
