(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 340 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 340 to 0 affect the standard deviation and interquartile range? What property does this illustrate?
