Commuting Times in Various Locations Essay Assignment
To compare commuting times in various locations, independent random samples were obtained from the six cities presented in the “Longest Commute to Work” graphic on page 255 in your textbook. The samples were from workers who commute to work during the 8:00 a.m. rush hour. One-way Travel to Work in Minutes
Atlanta Boston Dallas Philadelphia Seattle St. Louis 29 18 42 29 30 15 21 37 25 20 23 24 20 27 26 33 31 42 15 25 32 37 39 23 37 32 20 42 14 33 26 34 26 18 48 35
Construct a graphic representation of the data using six sid-by-side dotplots.
Visually estimate the mean commute time for each city and locate it with an X.
Does it appear that different citites have different effects on the average amount of time spent by workers who commute to work during the 8:00 a.m. rush hour? Explain.
Does it visually appear that different cities have different effects on the variation in the amount of time spent by workers wo commute to work during the 8:00 a.m. rush hour? Explain.
Calculate the mean commute time for each city depicted.
Does there seem to be a difference among the mean one-way commute times for these six cities?
Calculate the standard deviation for each city’s commute time.
Does there seem to be a difference among the standard deviations between the one-way commute times for these six cities?
Construct the 95% confidence interval for the mean commute time for Atlanta and Boston.
Based on the confidence intervals found does it appear that the mean commute time is the same or different for these two cities (Atlanta and Boston). Explain
Construct the 95% confidence interval for the mean commute time for Dallas.
Based on the confidence intervals found in (Atlanta and Boston) and Dallas does it appear that the mean commute time is the same or different for Boston and dalls? Explain.
Based on the confidence levels found in (Atlanta and Boston) and (Dallas) does it appear that the mean commute time is the same or different for the set of three cities, Atlanta, Boston, and Dallas? Explain
How doe your confidence intervals compare to the intervals given for Atlant, Boston, and Dallas in “Longest Commute to Work” on page 255?
Interstate 90 is the longest of the east-west U.S. interstate highways with its 3,112 miles stretching from Boston, MA at I-93 on the eastern end to Seattle WA at the Kingdome on the western end. It travels across 13 northern states; the number of miles and number of intersections in each of those states is listed below.
State No. of Inter Miles WA 57 298 ID 15 73 MT 83 558 WY 23 207 SD 61 412 MN 52 275 WI 40 188 IL 19 103 IN 21 157 OH 40 244 PA 14 47 NY 48 391 MA 18 159
Construct a scatter diagram of the data.
Find the equation for the line of best fit using x= miles and y=intersections.
Using the equation found in part (b), estimate the average number of intersections per mile along I-90.
Find a 95% confidence interval for β1.
Explain the meaning of the interval found in part d.
Not all countries have moved through all four phases of the demographic transition. You are a consultant for a developing country that is not yet in phase IV of demographic transition.
In your own words, complete the following:
Define demographic transition.
Describe the 4 phases of demographic transition, including if the population is stable, growing, or declining in each. ·
According to demographers, what factors lead to a decline in the crude birth rates (CBR) and crude death rates (CDR) in the epidemiologic and fertility phases of the demographic transition? ·
Briefly describe three living conditions and/or environmental impacts in developed countries that have reached phase IV, and contrast them with these conditions or impacts in developing countries that remain in earlier phases. ·
Assuming that the demographic transition phase IV is a goal for developing countries, what two programs or initiatives would you suggest to assist them in progress toward this goal?
