A screw conveyor model NS 324 is used to move dry ground corn. A test was conducted to relate the conveyor capacity in liters per second to the conveyor speed in revolutions per minute. The test results are shown below.

Write a script that plots this xy data. Label the x axis and the y axis. Also, place a title on the plot.
The general equation for the distance that a freefalling body has travelled (neglecting air friction) is:
Assuming that g=9.8m/s^{2}. Plot distance versus time for t=0100 seconds. Create three subplots, using linear coordinates, loglog coordinates and except a log scale is used for the Yaxis (using the command loglog and semilogy), respectively. Label the axes and give titles to the plots. Save the figure as JPEG file.
Use MATLAB to solve the following problem:
There are some exam grade data for three lab sections.

Write a script to analyze the data. The script must:
q Construct a histogram with 8 bins, axis labels, title, and legend.
q Determine the mean, median, min, max, and standard
deviation for each production line sample (HINT: To get help try help stats
or use lookfor, e.g. >> lookfor 'standard deviation').
With the following monthly average temperature, create a bar chart and set the xaxis ticklabel with the corresponding month, i.e. Jan, and Feb.
