The first clzxx in a relative frequency table is 50-59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate?

The value 0.2 in the relative frequency table indicates the proportion or percentage of data that falls within the first class interval, which in this case is the interval 50-59. The relative frequency is calculated by dividing the frequency of the class interval by the total number of data points.

To find the total number of data points, you will need the sum of frequencies for all class intervals in the table. Each class interval represents a range of values, and the frequency is the number of data points that fall within that range.

Once you have the total frequency, you can calculate the relative frequency for the first class interval by dividing the frequency of the first interval by the total frequency. In this case, if the frequency of the 50-59 interval is, for example, 10, and the total frequency is 50, then the relative frequency would be 10/50 = 0.2, or 20%.

So, the value 0.2 tells you that 20% of the total data points fall within the range of 50-59.
