A cellular phone company monitors monthly phone usage. The following data represent the monthly phone use in minutes
of one particular customer for the past 20 months. Use the given data to answer parts (a) and (b).
327 528 497 377 322
347 487 434 559 518
494 357 461 523 553
417 521 382 475 364
(a) Determine the standard deviation and interquartile range of the data.
s= (Round to two decimal places as needed.)
IQR= (Type an integer or a decimal.)
(b) Suppose the month in which the customer used 327 minutes was not actually that customer's phone. That particular month the customer did not use their phone at
all, so 0 minutes were used. How does changing the observation from 327 to 0 affect the standard deviation and interquartile range? What property does this
illustrate?
