last summer, maya was a lifeguard at the ginger hill community pool. she checked the temperature of the pool each morning. this box plot shows the results. pool temperature (°f) what percent of the mornings was the pool temperature 80°f or higher? % submit
Answer
Answer:
75
Explanation:
Step1: Recall box - plot properties
A box - plot divides data into quartiles. The first quartile ($Q_1$) represents the 25th percentile, the median ($Q_2$) represents the 50th percentile, and the third quartile ($Q_3$) represents the 75th percentile.
Step2: Identify relevant values
In the box - plot, 80°F is at the first - quartile ($Q_1$) value.
Step3: Calculate the percentage
The percentage of data that is 80°F or higher is 100% - 25% = 75%.
