Unfortunately, it is appropriate to use the Empirical Rule on only one of them! Answer the parts below to help Pablo with his approximations. (a) Identify the data set for which it is appropriate to use the Empirical Rule. ك It is appropriate to use the Empirical Rule for the (Choose one) data set. For the data set identified in part (a), use the Empirical Rule to make the following approximations. (b) The percentage of times between 36.5 minutes and 52.44 minutes is approximately (Choose one) ▼ (c) Approximately 99.7% of the times are between ☐ minutes and ☐ minutes.
