**Old Faithful Geyser Dormancy Periods Analysis**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, of 30 dormancy periods that occurred during a recent year:| 91 | 99 | 99 | 83 | 99 | 86 | 90 | 96 | 88 ||-----|-----|-----|-----|-----|-----|-----|-----|----|| 93 | 88 | 86 | 92 | 116 | 59 | 101 | 90 | 71 || 103 | 97 | 82 | 91 | 89 | 61 | 96 | 66 | 66 || 105 | 90 | 90 | | | | | | |This dataset can be useful for analyzing the intervals between eruptions and understanding patterns in Old Faithful's activity. Educators and students can use this information for statistical analysis, graphing exercises, and exploring natural geothermal phenomena. ### Frequency Distribution Construction for Educational Purposes#### Task:Construct a frequency distribution using a class width of 5, and using 55 as the lower class limit for the first class.#### Columns and Content- **Dormancy Period**: This column represents the range of time periods (intervals) for which the frequency distribution needs to be constructed.- **Frequency**: This column indicates the number of observations that fall within each interval or class.This table is structured to facilitate the calculation of the frequency distribution with defined class widths and well-organized intervals.#### Table Format:| Dormancy Period | Frequency ||-----------------|-----------|| - | - || - | - || - | - || - | - || - | - || - | - || - | - || - | - || - | - || - | - || - | - |#### Instructions:- **Class Width**: The class width is defined as 5.- **Initial Class Limit**: Start the first class at 55.#### Steps:1. **Identify the Lower Limit**: Begin with 55 as the lower limit of the first class.2. **Increase by Class Width**: Add the class width (5) to the lower limit to get the upper limit of the first class.3. **Repeat**: Continue this approach to create subsequent classes until all data is covered. For example:- **First Class**: 55-59 - **Second Class**: 60-64- And so on.Each row should then be filled with the corresponding frequency data, representing the number of observations within each dormancy period interval.This structured approach helps in organizing data into a frequency distribution, which is fundamental for various statistical analyses and graphical representations, such as histograms.

Solution-: Given: Class width =5 and use 55 as the lower class limit for the first class We want to…

American Time Use Șurvey 20. Aluminum Bottles The aluminum bottle, first introduced in 1991 by CCL Container for mainly personal and household items such as lotions, has become popular with beverage manufacturers. Besides being lightweight and requiring less nackaging, the aluminum bottle is reported to cool faster and stav cold longer than typical glass bottles. A small brewery tests this claim and obtains the following information regarding the time (in minutes) required to chill a bottle of beer from room temperature (75°F) to serving temperature (45°F). Construct and interpret a 90% confidence interval for the mean difference in cooling time for clear glass versus aluminum.
