A comparison between species: Biologists comparing the gestation period of two newly discovered species of frog collected data from 11 frogs of species A and 24 frogs of species B. Species A exhibited an average gestation period of 12 days with a standard deviation of 3.2 days while species B had a gestation period of 15 days and a standard deviation of 3.6 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 = 0.01. a) The hypotheses for this test are: O Họ: HA - H8 = 0 Hạ: HA - H8 > 0 O Họ: HB = 12 Hạ: H8 = 12 O Họ: HA - PB = 0 Ha: HA - PB < 0 %3D O Họ: HA - H8 = 0 Hạ: 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 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 O There is significant evidence that suggests no difference in the lengths of the gestational periods. O The lengths of the gestational periods are the same. O There is significant evidence to suggest a difference between the lengths of the two species' gestational periods
