Question

An Agricultural company wants to see if bees carrying diseases for the plants. Group of n bees were investigated for carrying some disease. Xi is a sequence. A sequence of indicators of those trials, X; = (1 for success or 0 if not), is available for n independent bees. X;=1 or 0). 1 is equal to success and 0 is equal to failure. Reciprocal Probability is R=1/p and it reflects the number of trials needed to obtain an expected time of a first success. It is essential to organize farms and staffing to make sure there is enough available employees when that disease cause problems in other farms. a) If n=9 and 4 bees were infected then find the 95% CI (confidence interval) for R? b) Based on the record X1,..., X, what is the unbiased estimation of R?
