Each observation in a random sample of 102 bicycle accidents resulting in death was classified according to the day of the week on which the accident occurred. Data consistent with information are given in the following table. Based on these data, is it reasonable to conclude that the proportion of accidents is not the same for all days of the week? Use α = 0.05. (Round your answer to two decimal places.)

A single observation of a random variable (that is, a sample of size n = 1) having a geometric distribution is used to test the null hypothesis θ = θ0 against the alternative hypothesis θ = θ1 for θ1 < θ0. The null hypothesis is rejected if the observed value of the random variable is greater than or equal to some positive integer k. Find expressions for the probabilities of type I and type II errors.
