Here are the top 20 salaries (in millions of dollars) of CEOs in 2018. Complete parts (a) through (e) below. For part (a) and (b), begin with lower class limit 30 million dollars and class width 10 million dollars. 37.5 & 36.3 & 53.6 & 42.4 & 42.8 68.4 & 40.7 & 49.0 & 45.1 & 67.2 61.0 & 103.2 & 41.5 & 34.5 & 40.8 35.9 & 70.6 & 42.2 & 43.2 & 102.2 a. Construct a frequency table. (Type integers or decimals. Do not round.)

To construct a frequency table, we need to determine the classes based on the given lower class limit and class width. The lower class limit is 30 million dollars, and the class width is 10 million dollars.<br /><br />Here are the steps:<br /><br />1. Determine the class intervals:<br /> - 30 - 39.9<br /> - 40 - 49.9<br /> - 50 - 59.9<br /> - 60 - 69.9<br /> - 70 - 79.9<br /> - 80 - 89.9<br /> - 90 - 99.9<br /> - 100 - 109.9<br /><br />2. Tally the number of CEO salaries that fall into each class interval.<br /><br />Frequency Table:<br /><br />\[<br />\begin{array}{|c|c|}<br />\hline<br />\text{Class Interval (in millions)} & \text{Frequency} \\<br />\hline<br />30 - 39.9 & 5 \\<br />40 - 49.9 & 9 \\<br />50 - 59.9 & 1 \\<br />60 - 69.9 & 3 \\<br />70 - 79.9 & 2 \\<br />80 - 89.9 & 0 \\<br />90 - 99.9 & 0 \\<br />100 - 109.9 & 2 \\<br />\hline<br />\end{array}<br />\]<br /><br />So, the frequency table is as follows:<br /><br />- 30 - 39.9: 5<br />- 40 - 49.9: 9<br />- 50 - 59.9: 1<br />- 60 - 69.9: 3<br />- 70 - 79.9: 2<br />- 80 - 89.9: 0<br />- 90 - 99.9: 0<br />- 100 - 109.9: 2
