A student placed 180 F water in each of four different types of cups and

measured the difference in temperature of the water after 30 minutes to see

which type of cup was more effective at maintaining temperature. She repeated

the procedure eight times. Use the following boxplots to answer the questions.

a)

Which type of cup lost the most temperature in a single observation?

b)

On average, which type of cup retained the most temperature?

c)

Which type of cup had the most variability in temperature changes?

d)

Which type of cup would you recommend to keep coffee hot longer & more

consistently?
