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). (a) Determine the standard deviation and interquartile range of the data. s 71.89 (Round to two decimal places as needed.) IQR 95 (Type an integer or a decimal.) (b) Suppose the month in which the customer used 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 to 0 affect the standard deviation and interquartile range? What property does this illustrate? The standard deviation increases and the interquartile range is not affected. What property does this illustrate? Choose the correct answer below.
