A city wants to encourage downtown employees to use public transportation. Below is the time in minutes to get to work on one morning according to whether the employee used public transportation or drove a car:
Public Transportation : 23 25 25 30 31 31 32 33 35 36 37 42
Private Transportation: 32 32 33 34 37 37 38 38 38 39 40 44
a)Calculate the mean, median for each group.
my solution :
the mean for public transportation = 31.6
the mean for private transportation = 36.8
the median for public transportation = 31.5
the median for private transportation = 37.5
b) Find the lower and upper-quartiles, and the inter-quartile range for each group.
my solution :
lower quartile for public transportation = 27.5
upper quartile for public transportation = 35.5
inter-quartile range for public transportation = 8
lower quartile for private transportation = 33.5
upper quartile for private transportation = 38.5
inter-quartile range for private transportation = 5
c)Calculate the standard deviation for each group.
