h4lp with stats homework A journal reported on an emergency

A journal reported on an emergency response system for incidents involving toxic chemicals in one country. The system has logged over 250 incidents since being implemented. The linked table gives a breakdown of the locations where these incidents occurred. Consider the location of toxic chemical incident in the country. Complete parts a through e below. Click the icon to view the breakdown. a. List the sample points for this experiment. Choose the correct answer below OA School laboratory, Chemical plant, Nonchemical plant, Other OB. School laboratory, In transit, Chemical plant, Nonchemical plant, Other OC. School laboratory, In transit, Chemical plant, Other OD. School laboratory, In transit, Chemical plant, Nonchemical plant b. Assign reasonable probabilities to the sample points. Let P(A) be the probability for the first sample point listed in part a, P(B) be the second sample point listed, and so on, until probabilities for all of the sample points are listed. Select the correct choice below and fill in the answer boxes within your choice. Type integers or decimals.) P(A) P(B) P(A) P(B)L P(D)- PCE)-

Solution

(a) B

All the categories listed in the table.

(b)

P(A)= 8/100 =0.08

P(B)= 28/100 =0.28

P(C)= 22/100 =0.22

P(D)= 30/100 =0.30

P(E)= 12/100 =0.12

(c)

P(School laboratory)=P(A)=0.08

(d)

P(chemical plant or non-chemical plant)= (22+30) / 100 =52/100 =0.52

(e)

P(Not in transit) = 1-P(in transit) =1-0.28 =0.72
