How do I determine if individuals walk at different speeds depending on whether they are departing or arriving at the α = 0.1 level of?significance? If I was to let μ1 represent the mean speed of people departing and μ2 represent the mean speed of people arriving. What would be the null and alternative hypothesis?
Direction of Travel Departure Arrival
Mean Speed 253 270
(Feet per minute)
Standard deviation 48 31
(Feet per minute)
