Answer:
(a) H0: mu = 17 vs. Ha: mu < 17
(b) Sample statistic is 1.6
Explanation:
(a) A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) the upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from a population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
(b) Sample statistic = sample mean ÷ sample size = 16 ÷ 10 = 1.6
The two fundamental principles used in building cladograms are principles of parsimony and robusticity.
The principle of parismony states that the simplest of competing explanations is the one most likely to be correct.
The principle of rubusticity states that trees that maintains their basic forms even when different options are applied to the sequence of changes in one or more of their branches are preferable.<span />
They are homologous characteristics.
