able to easily calculate the actual percent of dropped calls directly from the entire database of millions of calls. So, you decide to take a random sample of 2500 calls, and each call is classified as "dropped" or "not dropped". Of the 2500 calls examined, 1.462% of them were classified as "dropped". Calculate the appropriate test statistic. Enter with 2 decimals (eg. 1.96).

![A cell phone service provider claims that only 1% of their calls get "dropped" (i.e., neither party
hangs up, but the connection is lost). You work for the Consumer Protection Agency, and
believe that the percent of dropped calls from this provider is higher than 1%. Your agency has
been granted access to this company's detailed call records. It takes careful examination of each
call transaction to determine if the call can be considered a "dropped call", so you are not able to
