at a t - shirt stand on the boardwalk, 5 of the last 15 shirts sold were gray. considering this data, how many of the next 12 shirts sold would you expect to be gray? shirts
Answer
Explanation:
Step1: Calculate the proportion of gray - shirts
The proportion of gray shirts in the first 15 sold is $\frac{5}{15}=\frac{1}{3}$.
Step2: Use the proportion to predict
Multiply the proportion by the number of next - sold shirts. So the expected number of gray shirts in the next 12 sold is $\frac{1}{3}\times12 = 4$.
