Q2 Multiple Choice You are going fishing. For each of the following random variables, select the distribution (Binomial, Geometric, Poisson, Exponential, or Normal) that best characterizes or approximates it. Q2.1 You catch an expected number of 1.5 fish per hour. You can catch a fish at any instant of time. Which distribution best characterizes the number of fish you catch in one hour of fishing? O Binomial O Geometric O Poisson O Exponential O Normal Save Answer Q2.2 You catch an expected number of 1.5 fish per hour. You can catch a fish at any instant of time. Which distribution best characterizes how the amount of time it takes to catch a fish after casting the line? O Binomial O Geometric O Poisson O Exponential O Normal Save Answer Q2.3 Each day you fish for 2 hours. Assume that the numbers of fish you catch each day are independent. Which distribution best characterizes the number of days until you catch more than 10 fish in one day? O Binomial O Geometric O Poisson O Exponential O Normal Save Answer Q2.4 Each day you fish for 2 hours. Assume that the numbers of fish you catch each day are independent. Which distribution best characterizes the number of days you catch no fish over a week of fishing? O Binomial O Geometric O Poisson O Exponential O Normal Save Answer Q2.5 The probability that you catch at least x fish in a year is approximately 1 (t-5002 e 200 dt. 1002 S. Which distribution best approximates the number of fish you catch each year? O Binomial O Geometric O Poisson O Exponential O Normal Save Answer

Answer 1

2.1) Poisson distribution

2.2) exponential distribution

2.3) Geometric distribution (since trail continues untill 1st success appears)

2.4)Binomial distribution

2.5) Normal distribution
