Do individuals walk at different speeds depending on whether they are departing or arriving at the α = 0.01 level of significance? Let μ1 represent the mean speed of people departing and μ2 represent the mean speed of people arriving. (a) State the null and alternative hypothesis.

Do people walk faster in an airport when they are departing (getting on a plane) or after they have arrived (getting off a planej? An interested passenger watched a random sample of people departing and a random sample of people arriving and measured the walking speed (in feet per minute) of each. What type of study desig is being performed? Choose the correct answer below 0 A, completely randomized experimental design O B. observational study O C. randomized block experimental...
8. (4 pts) Researcher measured the walking speed of travelers in San Francisco International Airport and Cleveland Hopkins International Airport. The standard deviation speed of the 35 travelers who were departing was 53 feet per minute. The standard deviation speed of the 35 travelers who were arriving was 34 feet per minute. Assuming walking speed is normally distributed, does the evidence suggest the standard deviation walking speed is different between the two groups? Use the a = 0.05 level of...
In a previous year, 63% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 600 females aged 15 and older and finds that 387 are living alone. Is there sufficient evidence at the a = 0.05 level of significance to conclude the proportion has changed? Because npo (1-Po - U V 10, the sample size is V 5% of the population size, and the sample the...
