Solution Steps

Step 1: Construct a Relative Frequency Distribution

To construct a relative frequency distribution, we divide the number of players in each speed range by the total number of players. For speed range 10-13.9 km/hr, the relative frequency is calculated as 3 / 641 = 0 For speed range 14-17.9 km/hr, the relative frequency is calculated as 8 / 641 = 0.01 For speed range 18-21.9 km/hr, the relative frequency is calculated as 18 / 641 = 0.03 For speed range 22-25.9 km/hr, the relative frequency is calculated as 72 / 641 = 0.11 For speed range 26-29.9 km/hr, the relative frequency is calculated as 305 / 641 = 0.48 For speed range 30-33.9 km/hr, the relative frequency is calculated as 235 / 641 = 0.37

Step 2: Construct a Frequency Histogram

A frequency histogram is constructed with speed ranges on the x-axis and the number of players on the y-axis. Each bar represents a speed range, and the height of the bar corresponds to the number of players in that range. Speed Range: 10-13.9 km/hr, Number of Players: 3 Speed Range: 14-17.9 km/hr, Number of Players: 8 Speed Range: 18-21.9 km/hr, Number of Players: 18 Speed Range: 22-25.9 km/hr, Number of Players: 72 Speed Range: 26-29.9 km/hr, Number of Players: 305 Speed Range: 30-33.9 km/hr, Number of Players: 235

Step 3: Construct a Relative Frequency Histogram

A relative frequency histogram is similar to the frequency histogram, but the height of each bar corresponds to the relative frequency of players in each speed range. Speed Range: 10-13.9 km/hr, Relative Frequency: 0 Speed Range: 14-17.9 km/hr, Relative Frequency: 0.01 Speed Range: 18-21.9 km/hr, Relative Frequency: 0.03 Speed Range: 22-25.9 km/hr, Relative Frequency: 0.11 Speed Range: 26-29.9 km/hr, Relative Frequency: 0.48 Speed Range: 30-33.9 km/hr, Relative Frequency: 0.37

Step 4: Calculate Specific Percentages

To find the percentage of players within a specific speed range, multiply the relative frequency by 1. Percentage of players in speed range 10-13.9 km/hr: 0% Percentage of players in speed range 14-17.9 km/hr: 1% Percentage of players in speed range 18-21.9 km/hr: 3% Percentage of players in speed range 22-25.9 km/hr: 11% Percentage of players in speed range 26-29.9 km/hr: 48% Percentage of players in speed range 30-33.9 km/hr: 37%

Final Answer:

The analysis includes a relative frequency distribution, a frequency histogram, a relative frequency histogram, and the calculation of specific percentages within the speed ranges.
