A comparison between species: Biologists comparing the gestation period of two newly discovered species of frog collected data from 13 frogs of species A and 23 frogs of species B. Species A exhibited an average gestation period of 10 days with a standard deviation of 3.6 days while species B had a gestation period of 16 days and a standard deviation of 4 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: Ho: HA - HB = 0 Ha: HA - HB > 0 Ho: HA - HB = 0 Ha: HA - HB < 0 Но: Ив 3D 10 На: Ив 10 Họ: HA - HB = 0 Ha: HA - HB = 0 What is the test statistic for this test? test statistic (Report answer accurate to 2 decimal places.)

Question
Transcribed Image Text:A comparison between species: Biologists comparing the
gestation period of two newly discovered species of frog
collected data from 13 frogs of species A and 23 frogs of
species B. Species A exhibited an average gestation period
of 10 days with a standard deviation of 3.6 days while
species B had a gestation period of 16 days and a standard
deviation of 4 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:
Ho: HA - HB = 0
Ha: HA - HB > 0
Ho: HA - HB = 0
Ha: HA - HB < 0
Но: Ив 3D 10
На: Ив 10
Họ: HA - HB = 0
Ha: HA - HB = 0
What is the test statistic for this test?
