T-shirt Color Frequency Relative Frequency Black 7 720 = ?% White 3 320 = ?% Blue 10 1020 = ?% Summarize the data in this relative frequency table using a percent bar graph. Which graph shows the data in the table?

Answer 1

To calculate the percentages, we can use the formula:

Relative Frequency = Frequency / Sum of Frequencies

For Black:
Relative Frequency = 7 / (7 + 3 + 10) = 7 / 20 = 35%

For White:
Relative Frequency = 3 / 20 = 15%

For Blue:
Relative Frequency = 10 / 20 = 50%

To create a percent bar graph, we can use a horizontal bar graph where the x-axis represents the different colors and the y-axis represents the percentage of each color. The length of each bar will be proportional to the relative frequency of each color. In this case, the blue bar will be the longest, followed by black, and then white.
