Consider the following frequency distribution Class Frequency 1000 up
Consider the following frequency distribution:
Class ....... Frequency
1000 up to 1100 ..... 2
1100 up to 1200 ... 7
1200 up to 1300 ... 3
1300 up to 1400 .... 4
a. Construct a relative frequency distribution. What percent of the observations are at least 1100 but less than 1200?
b. Construct a cumulative frequency distribution and a cumulative relative frequency distribution. How many of the observations are less than 1300?
c. Graph a frequency histogram.
