a. Box-and-Whisker Plot:
|----------------------*----|----*------|------*---------|----------*-----|----*---------|----------------*---|---*---------------|---------------*---|----|
b. Median Temperature: The median temperature is 73.5 degrees Fahrenheit.
c. 75% of the temperatures are below what value: To find this value, we look at the box-and-whisker plot. 75% of the temperatures are below the upper quartile (Q3), which is approximately 86 degrees Fahrenheit.
d. 75% of the temperatures are above what value: 25% of the temperatures are below the lower quartile (Q1), which is approximately 55 degrees Fahrenheit. Therefore, 75% of the temperatures are above 55 degrees Fahrenheit.
e. Conclusions:
- The temperature in Maryland varies significantly throughout the year, with the highest temperatures being in July and August, and the lowest temperatures being in January and December.
