A comparison between species: Biologists comparing the gestation period of two newly discovered species of frog collected data from 15 frogs of species A and 22 frogs of species B. Species A exhibited an average gestation period of 14 days with a standard deviation of 3.3 days while species B had a gestation period of 19 days and a standard deviation of 3.2 days. The researchers want to know whether the average lengths of the gestational periods differ between the two species. Conduct a hypothesis test at a significance level of a = 0.05. a) The hypotheses for this test are: Ho: HB = 14 Ha: HB 14 Ho: HAHB=0 Ha: HA HB < 0 Ho: HA-HB = 0 Ha: HA HB = 0 OHO: HA-HB=0 Ha: HA HB > 0 What is the test statistic for this test? test statistic = (Report answer accurate to 2 decimal places.) What is the p-value for this test? p-value= (Report answer accurate to 4 decimal places.)
The decision reached is O Fail to reject Ho O Reject Ho and accept Ha As such, the final conclusion is that O There is not significant evidence to suggest a difference between the lengths of the two species gestational periods There is significant evidence that suggests no difference in the lengths of the gestational periods. There is significant evidence to suggest a difference between the lengths of the two species gestational periods O The lengths of the gestational periods are the same.
