Question
Consider the distnbution of the annual ainfal in 114 cibics selected randomly throughout the United States. Complete parts (a) through (d) below a. How many peaks would you expect for the distrbution? OA. There woukl probably be one peak because these ane no obvious reasons why the values of the annual raintal would loem diflerent geoups O B. There woukl probably be three peaks, one for the cities with tle tainfall, one for the cities with average rainfal and one for the cities with a lot of tainfal. C. There would probably be no peaks. The annual rantal tend to form a uniform dotrbuton. O D. There wauld probably be many peaks comresponding to the ditferent amounts ot raintall in each city b. Make a sketch of the distribution. Choose the comect answer below O A. . . O D. c. What shape would you expect for the diatrbution? A The distribution would probably be right-skewed because there a clear mrmum amount of ramal but no obvious maxmum amount. O B. The distnbution would probabhy be symmetric because there are no obvious factors to indicate that there would be more or less rainfall in any city ° C. The distribution would probably be symmetric because al the Cities would tend to have neaty the same amount of antal. D. The distribution would probably te left-skewed because these is a clear minimum amount of fatal but no otvous maximum amount. d. What variation would you expect in the distnbution? OA. The variation would probably be moderate because all the cities would send to have nearly the same amount of rainfal O B. The variation would probably be large because there would ikely be several cities with very difierent amounts of rainfal O C. The vanation would probably be smal because al the ciries would tend to have nearly the same amount of raintal D. The variation would probably be moderate because there are no obvious ieasons to expec an especialy large or smal amount of va aion.Explanation / Answer
Q.1
OPTION A
THERE WILL BE ONLY ONE PEAK IN THE DISTRIBUTION AS THERE ARE NO OBVIOUS REASON FOR THE RAINFALL DATA TO FORM GROUPS.
Q.2
OPTION B
GRAPH B IS CORRECT AS IT IS A ONE PEAK GRAPH AND MAXIMUM WILL BE BOUNDED MEANING IN THE RIGHT SIDE GRAPH WILL HAVE ITS EXTRIMITY.
Q.3
OPTION A
DISTRIBUTION WILL BE RIGHT SKEWED AS THERE IS CLEAR MINIMUM BUT NOT OVBIOUS MAXIMUM.
Q.4
OPTION C
VARIATION WOULD BE SMALL AS MOST OF THE CITIES TENDS TO HAVE SAME RAINFALL.
