Consider a population of frogs living on an island. We believe that the frogs may be members of a species call Rana Pipiens. The mean length of Rana Pipiens is known to be 11cm. The following length values (cm) were obtained for a sample of individuals from the island: 11.9 9.9 10.6 10.9 10.1 10.7 9.8 10.2 10.6 11.0 12.2 11.2 10.5 9.9 9.7 10.8 10.5 11.2 9.5 11.2 Conduct a two-tailed t-test of this data. Q7. What is the absolute value of the t calculated value you obtain? tcalc = ??? (provide value to nearest 0.0001) Q8. Do these frogs have sizes that are consistent with their being Rana Pipiens or not? Base your decision on whether the mean length of the island frogs is as expected. You will be presented with a set of choices and must choose the correct one. Your choices will be: () The mean length is significantly less than 11 cm ( 0.05
