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 2955 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/ — X 0 percentage frequency _ sum of all frequenc1es 1938 2955 65.6% X 100% The frequency of female survivors is 431. Substitute the frequency into the relative frequency formula and calculate the relative frequency as a percentage, rounding to one decimal place. category frequency 1000/ — x 0 percentage frequency , , , sum 01 all trequenc1es 431 2955 l4.6% X 100% The frequency of females who died is I60. Substitute the frequency into the relative frequency formula and calculate the relative frequency as a percentage, rounding to one decimal place.
