I need help with these when someone gets a chance, thanks! t

Multiple Choice. The nal questions are based on the following scenario. A railroad hack runs alongside a farmer's eld, and passing trains sometimes emit sparks that cause res which damage the farmer's crops. Suppose that the railroad can take one ofthree actions: {1] no action; {2] install a spark arrester at a cost of $50; {3} stop running trains at a cost of200. The following table shows the costs ofthese actions to the RR and the impacts 1hat the}.r have on the probability ofa re. The cost ofa re in all cases is $150. Action Cost to RR ProIJIahilitj.r ofa re Loss to farmer om a re {1} No action :5 0 1 $150 {2) Install an arrester $ 50 .50 $150 {3) Stop mnning trains $200 0 $150 _ 22. The action that minimizes total expected accident costs is {a} No action. {b} Install an arrestecr. {c} Stop running trains. {:1} Costs are equal under all three options. _ 23. The total cost resulting om this cost-minimizing action is {a} $125. {b} $150. {c} $200. {:1} $3 50. _ 24. Suppose 1he Hand test is used to compare \"Install an attester\" and \"No action." We compute E and PL in this case as follows: {a} B=$ and PL=$150 {b} B=$ and PL=$25 {c} E=$50 and PL=lil 50 {d} E=$50 and PL=$T5 _ 25. Now suppose the Hand test is used to compare \"Stop running trains\" and \"Install an attester.\" In this case, B and PL are: {a} a=$aoa and PL =$150 {b} E=$150 and PL =$1aa {c3 a=$150 and PL=$TS {a} a=$5o and PL =53
