Exercise

Proportion of males admitted overall

Next we'll calculate the percentage of males and percentage of females admitted, by creating a new variable, called prop (short for proportion) based off of the counts calculated in the previous exercise and using the mutate() from the dplyr package.

Proportions for each row of the data frame we created in the previous exercise can be calculated as n / sum(n). Note that since the data are grouped by gender, sum(n) will be calculated for males and females separately.

The table of counts of gender and admission status you developed earlier is available as ucb_admission_counts.

  • Group the data by gender.
  • Create the new variable described above, prop, the proportion of males and females admitted.
  • Filter the data for those who are admitted so that the resulting data frame only contains proportions of males and females who are admitted.
  • Which gender has a higher admission rate, male or female?
