Hi I am in psychology/statistics and I need help with making a frequency table. So far I have listed all the numbers that were given to me and their respective frequencies, but I am not sure how to calculate the percentages? If you know how to do this please show/explain how to do this. Thanks so much.
Here are the instructions from my assignment: The Following are the speeds of 40 cars clocked by radar on a particular road in a
35-mph zone on a particular afternoon:
30 36 42 36 30 52 36 33 30 32 35 32 33 40 37 34 36 31 35 20 24 46 23 31 32 45 34 37 28 40 34 38 40 52 31 33 15 27 36 40.
(a) Make a frequency table
(b) Make a histogram
(c) Describe the general shape of the distribution
