The following study details will be used for questions 15-17. The information will be repeated for each question, and the values do NOT change. Knowing that African elephants are afraid of bees and that Kenyan farmers have successfully used hives to keep elephants from stomping crops, researchers wondered if the same technique would work for Asian elephants. A study published in Current Biology (https://www.cell.com/current-biology/references/S0960-9822(07)01718-6) "used a recording of a disturbed hive of cavity-dwelling Asian honey bees and conducted sound playbacks to 120 wild elephants in family groups resting under trees in Uda Walawe National Park in Sri Lanka." Bee sounds were played for 17 resting families of elephants, and 16 of them moved within 80 seconds of sound onset. Waterfall white noise was played for a 15 resting families, and 4 of them moved within 80 seconds. Is the proportion of elephants who move away from bee sounds within 80 seconds significantly greater than those who move away from white noise? Identify the ONE appropriate set of hypotheses.
15.) Select one
Select one:
a.H0: pbee= pwhite and H1: pbee> pwhite
b.H0: bee= white and H1: bee white
c.H0:p^bee =p^white and H1:p^bee >p^white
d.H0: pbee= pwhite and H1: pbee pwhite
e.H0:xbee=xwhite and H1:xbee>xwhite
16.) Select the ONE best choice. The test-statistic and p-value for the appropriatetest are:
Select one:
a.t= 3.93p-value = 4.1958
b.z= 3.93p-value = 0.00004
c.t= 3.93p-value = 0.00004
d.z= 3.93p-value = 0.99996
17.) Within the context of the study, clearly explain whether this is an observational study or an experiment as you would to a friend who has never studied statistics.
