A data set is summarized in the frequency table below. Using the table, determine the number of values greater than or equal to
swat32

The number of values greater than or equal to 8  is  mathematically given as

x = 27

This is further explained below.

<h3>What is a data set?</h3>

Generally, Simply put, data sets are groups of information. When dealing with tabular information, a data set is analogous to one or more database tables, where each column represents a different variable and each row represents a separate record.

In conclusion, the total amount of numbers that are either more than or equal to 8

Data value 8 is only exceeded by 9, 10, 11, and 12.

  • 8 occurs 4 times
  • 9 occurs 6 times
  • 10 occurs 8 times
  • 11 occurs 4 times
  • 12 occurs 5 times

Hence

x= 4+6+8+4+5

x = 27
