The geyser Old Faithful in Yellowstone National Park alternates periods of eruption, which typically last from 1.5 to 4 minutes, with periods of dormancy, which are considerably longer. The following table presents the durations, in minutes,30 of dormancy periods that occurred during a recent year.Construct a frequency distribution using a class width of 7, and using 55 as the lower class limit for the first class.

To construct a frequency distribution, we need to organize the given data into classes or intervals and count the number of observations falling within each interval.Given:Class width = 7Lower class limit for the first class = 55To construct the frequency distribution, we can proceed as follows:Step 1: Determine the class boundaries.Since the lower class limit is 55 and the class width is 7, we can calculate the class boundaries as follows:First class boundary = Lower class limit = 55Second class boundary = Lower class limit + Class width = 55 + 7 = 62Third class boundary = Lower class limit + 2 * Class width = 55 + 2 * 7 = 69And so on.Step 2: Count the number of observations falling within each interval and create the frequency table.Class Interval    Frequency[55,62)[62,69)[69,76)[76,83)[83,90)[90,97)[97,104)[104,111)[111,118)[118,125)
