confidence interval for difference of two proportions is needed using standard normal distribution(Z)
Step-by-step explanation
Here the main context is
need the difference between 'the proportion of the the first time flyers choose the aisle compared to the proportion of all other passengers'
So this is related difference between two proportions
in this case
