A phycologist is interested in testing the claim that the proportion of algae from a local rivulet that belonged to the particular phylum cyanobacteria is at least half. A random sample of 50 alga was obtained and each alga was categorized as either being cyanobacteria or not. It was found that 38 were, in fact, cyanobacteria. Please select any of the statements below which are TRUE. Answer 1. H subscript o colon space mu space greater or equal than space 50 percent sign H subscript 1 colon space mu space less than space 50 percent sign 2. H subscript o colon space p space greater or equal than space.50 H subscript 1 colon space p space less than space.50 3. The P-value for this hypothesis test is 3.68 4. For this hypothesis test since the P-value is less than or equal to alpha means we reject the null hypothesis. 5. For this hypothesis test, since the P-value is 0 we reject the null hypothesis. Therefore, we reject the claim that the proportion of algae from a local rivulet that belonged to the particular phylum cyanobacteria is at least half
