Question

The statement -- Researchers are interested to compare height of three species of rhino Asian, African, and Sumatran. These species are geographically isolated and believed to be different in their size. Twenty rhinos from each population were selected randomly and their height was measured.

From this statement for the one way ANOVA what is the Hypothesis?

.

Answer 1

Here,there are three population (species) of comparison

Population 1:height of species of rhino Asian

Population 2:height of species of African

Population 3:height of species of Sumatran

The Researchers are interested to compare height of three species of rhino Asian, African, and Sumatran

The means of these populations (species) are denoted by

: average height of species of rhino Asian

:average height of species of African

: average height of species of Sumatran

For One-way ANOVA hypothesis is

The Null and alternative hypothesis are

The rejection of null hypothesis means Atleast one species has average height is different
