Examine the data from a survey of farmers about their different soil types and the crops they prefer to grow. Using relative frequencies, what is the percentage chance that farmers with rocky soil prefer growing peppers? Round your answer to the nearest tenth.
Sandy soil, carrots- 120
Sandy soil, peppers- 50
Sandy soil, total- 170
Rocky soil, carrots- 100
Rocky soil, carrots- 150
Rocky soil, carrots- 250
Totals, carrots- 220
Totals, peppers- 200
Totals, total- 420
To find the percentage chance that farmers with rocky soil prefer growing peppers, we need to look at the relative frequency of farmers with rocky soil who prefer peppers.
Relative frequency = (Number of farmers with rocky soil who prefer peppers) / (Total number of farmers with rocky soil)
Relative frequency = 50 / 500
Relative frequency = 0.1
Therefore, the percentage chance that farmers with rocky soil prefer growing peppers is 10%.
