Instructor: Shawn Pan'ini  16 weeks
Date: 3."'18."'10 Book: T1‘iola: Elenlentaiy Statistics. 11c Time: 11:00 AM Use the given qualitative data to construct the relative frequency distribution. The 2955 people aboard a ship that sank include 426 male survivors, 1938 males who died, 43] female survivors, and
160 females who died. To calculate the relative frequency for each category as a percentage, use the formula shown below. cate o fre uenc
percentage frequency = X l00%
sum of all trequencres The sum of all the frequencies is the total number of people aboard the ship, 2955.
The category frequency for male survivors is the number of males who survived, 426. Use the relative frequency formula to calculate the relative frequency ofmale survivors as a percentage, rounding to one
decimal place. Substitute 426 for the category frequency and 2955 for the sum ofall frequencies. category frequency 100V percentage frequency _
sum of all frequenmes 426

14.4% x 100% The frequency of males who died is 1938. Substitute the frequency into the relative frequency formula and calculate the
relative frequency as a percentage, rounding to one decimal place. category frequency 1000/
