(a) Make a time-series line graph showing the trend of observed
rainfall data through time. (For year, just denote it as Year 1, Year 2
etc.). Draw the line graph by hand.
(b) Make a grouped data representing the given rainfall data. Use
the following class intervals: 40<=X<45, 45<=X<50, 50<=X<55,
55<=X<60, 60<=X<65, and 65<=X<70.
(c) Using the grouped data from (b), calculate the following:
o mean, median, and mode
o variance, standard deviation, coefficient of variation, first
