Final answer:
To construct a Frequency Distribution table using 5 classes, organize the data into a chart with five intervals of equal width and record the frequency of data points in each interval. To find the Median and Mode of insect lifetime, use the frequency distribution table. Sketch a Histogram and Cumulative Frequency Polygon (OGIVE) by plotting the class intervals and frequencies.
Step-by-step explanation:
To construct a Frequency Distribution table using 5 classes for the insecticide experiment, you need to organize the data into a chart with five intervals of equal width. Label the two columns as Enrollment and Frequency. Then, count the number of data points that fall within each interval and record the frequency in the Frequency column. To determine the Median and Mode of insect lifetime, you can use the frequency distribution table to find the midpoint of the data and the value that occurs most frequently, respectively. To sketch a Histogram and Cumulative Frequency Polygon (OGIVE), plot the class intervals on the x-axis and the frequencies on the y-axis. For the cumulative frequency polygon, plot the cumulative frequencies instead of the individual frequencies.
