Construct a relative frequency table of the data using the categories given.Give the relative frequencies rounded to three decimal places.

Answer 1

Answer:

Step-by-step explanation:

we can simply find the relative frequency as foloows:

We are given are No piercings, One or two piercings, and More than two piercings. The relative  frequency with no piercings is 188/361 = 0.521, the relative frequency for one or two piercings is 82/361 =  0.227. The total has to add to 361, so there are 361−188−82 = 91 students with more than two piercings,  and the relative frequency is 91/361 = 0.252. the below table describes each.
