Research Methods and Data Analysis I

You have been employed as the newest member of our guest speaker's Traffic Analysis team. pedestrian volumes were collected every hour within a 24-hr day. The volumes were collected in April, in an urban region of Toronto.

The following table shows the data taken from a sample of 1 day: Pedestrian volumes 271 218 170 103 671 1871 2598 2978 3844 4785 4002 4511 4220 4301 3230 3580 4617 4821 3544 3781 2984 1077 408 411

a)The sample mean is:

X=2624.833

b)The sample standard deviation is:

s=1741.85842

c)The confidence interval is:

CI=(1889.2956,3360.3704)

d)There is 95% chances that population means lies between 1889.2956 and 3360.3704.

e)Sample size is less than 30, so we cannot say that above sample mean volume estimation be accurate all year round.

UN's Sustainable Development Goal (SDG)

Goal #11 - Make cities and human settlements inclusive, safe, resilient, and sustainable

Discuss how the Traffic Analysis Team can use the above data to inform a more sustainable design of the city of Toronto to achieve one of the above goals.
