Give the answer as a decimal number with at least two decimal places.
Einar Óli has measured the area of scallops on two places in Breiðafjörður and used a t-test to investigate whether there is a difference in the area of scallops in those two places. A type-ll error occurred when Einar Óli conducted his hypothesis test. What happened? 1. There is no difference in the average area of scallops at those two places but Einar Óli rejected the alternative hypothesis and concluded that there difference. 2. There is no difference in the average area of scallops at those two places but Einar Óli concluded that there is a difference. 3. There is no difference in the average area of scallops at those two places but Einar Óli made no claims. 4. There is a difference in the average area of scallops at those two places but Einar Óli made no claims. 5. OR-command:
