1. Create a function file named ozoneAvg.m that calculate the average of the numbers in a given array (the function has one input and one output arguments) [1 point] 2. Create a script file and name it ozoneAnalysis.m (save it in the same folder with ozoneAvg.m function) [1 point] 3. Upload the Ozone.txt file to ozoneAnalysis.m and assign it to an array named ozoneData [1 point] 4. Use a for-end loop and if-end statements to find all the years with ozone concentration more than 0.075 ppm [hint: use ozoneData (k-1) and ozoneData (k,2) appropriately in the loop] a. Create a counter that count the number of years with ozone concentration above 0.075 ppm, name it above075 [1 point] b. Set up the for-end loop [lpoint] c. set up the if-end conditional statement [1point] d. Increase the above075 counter by one when the condition is met [1point] e. Use fprintf command to print each year with concentration above 0.075 and the average ozone concentration on that year. "The average concentration on XXXX was x.xxxx ppm" [1 point] f. Format the concentration so it is printed as x.xxxx for each year [1 point] g. Use fprintf command to print the number of years with concentration above 0.075 ppm. "The average ozone concentration was higher than 0,075 ppm for X years." [1 point] 5. Use a for-end loop and If-else-end statements to go through ozoneData. [hint: use ozone Data (k.1) and ozone Data (k.2) appropriately in the loop] a. Create a counter to find the number of years that meet 2015 standard, name it meet2015. [1 point] b. Create a counter to find the number of years that does not meet 2015 standard, name it violate2015 [1 point] C. Set up the for-end loop [lpoint] d. set up the if-else-end conditional statement [1point] e. Increase the meet2015 counter by one when the condition is met [1point] f. Increase the violate2015 counter by one when the condition is NOT met [lpoint] g. Use fprintf command and print "Ozone concentration on xxxx was x.xxxx ppm and it meets the 2015 standard" if ozone concentration is less than or equal to 0.070 ppm [1 point] h. Use fprintf command and print "Ozone concentration on xxxx was X.XXXX ppm and it violates the 2015 standard" if ozone concentration is more than 0.070 ppm [1 point] i. Use fprintf command to print the number of years with concentration less than or equal to 0.070 ppm. "The average ozone concentration was in compliance with the 2015 standard for X years." [1 point] j. Use fprintf command to print the number of years with concentration above 0.070 ppm. "The average ozone concentration violated the 2015 for X years." [1 point] 6. Create a vector named ozoneConc that ONLY contains the concentration column of ozoneData matrix (hint - use :) [1 point] 7. Create a vector named ozone Year that ONLY contains the year column of ozone Data matrix (hint - use :) [1 point] 8. Call the ozoneAvg function you created in step 1 to calculate the average of the items in ozoneConc [1 point] 9. Find the smallest and largest ozone concentration in ozoneConc vector [1 point] 10. Use fprintf to print the average ozone concentration "The average concentration of ozone between 1980 to 2018 is x.xxxx ppm". [1 point] 11. Use fprintf to print the smallest and largest ozone concentration. The smallest concentration was x.xxxx ppm and the largest concentration was x.xxxx ppm". [1 point] 12. Create a vector named "standard2015" with 39 elements all have a value of 0.07 (you can create it manually or using for-end loop) [1 point] 13. Plot the ozone Year on the x-axis and the ozoneConc in the y-axis. Show standard2015 in the same graph you created in step13. Plot the ozone Year on the x-axis and the standard2015 in the y-axis. [1 point] 14. Use dotted red line and * for the marks for the OzoneConc. Use dotted blue line and x for the marks of the standard2015. [1 point] 15. Make sure the graph contains title, x-label, y-label, and legend. Save the graph as pdf. Go to "Save As..." under "File" then change the "Save as Type:" to .pdf (don't keep it .fig) and name it ozoneGraph.pdf (save it in the same folder for the homework because you need to submit it for grading) [1 point] 16. Publish the script file to pdf by typing the following in the Command Window: publish (ozone Analysis, 'pdf), it will be saved in a folder named html inside the current folder (you need to submit ozone Analysis.pdf for grading) [1 point] \
