Tower of Terror Wait Times

a. Find Q1, Q2 and Q3.

In Exercises 1–5, refer to the following list of numbers of years that deceased U.S. presidents, popes, and British monarchs lived after their inauguration, election, or coronation, respectively. (As of this writing, the last president is George H. W. Bush, the last pope is John Paul II, and the last British monarch is George VI.) Assume that the data are samples from larger populations.

Exploring the Data Include appropriate units in all answers.

d. Are there any obvious outliers?

Cloud Seeding The “Florida Area Cumulus Experiment” was conducted by using silver iodide to seed clouds with the objective of increasing rainfall. For the purposes of this exercise, let the daily amounts of rainfall be represented by units of rnfl. (The actual rainfall amounts are in or )

Find the value of the following statistics and include appropriate units based on rnfl as the unit of measurement.

Which of the following distributions is left skewed when displayed on a graphing calculator?

Which of the following types of data can be measured quantitatively?

Suppose you have entered a data set into your graphing calculator and want to determine how many data values fall within the range from $35$ to $95$, inclusive. Which calculator function or process would you most likely use to find this count?
