You will evaluate the claim that 70% of the plant species in a region are epiphytic, on the basis of an independent sample that you will obtain of size n=8. In the table below, find possible values of the number of epiphytic species in your sample (x), together with the resulting p-values and probabilities assigned by the null hypothesis. If you use significance level 0.1, what is closest to the probability of a type I error for your test? Suppose that you carry out the test in the previous problem and that, unbeknownst to you, the percentage of epiphytic species is not actually equal to 70% . Which is true of the probability of a type II error
