To interpret, there were 50 days on which no credit applications were received, 77 days on which only one application was received,
and so on. Would it be reasonable to conclude that the population distribution is Poisson with a mean of 2.0? Use the 0.05 significance
level. Hint. To find the expected frequencies use the Poisson distribution with a mean of 2.0. Find the probability of exactly one
success given a Poisson distribution with a mean
of days in which there was exactly one application. Determine the expected frequency for the other days in a similar manner.
2.0. Multiply this probability by 300 to find the expected frequency for the number
Ha: Distribution with Poisson with u= 2.
H: Distribution is not Poisson with u= 2
a. State the decision rule. Use 0.05 significance level. (Round your answer to 3 decimal places.)
