Hypothesis Testing (Mean) with a Single Population
In statistics, a hypothesis is a claim or a statement about
the property of an underlying population.
The approach involves making a tentative assumption
about the population parameter, which is usually referred
to as the null hypothesis and denoted by Ho.
Another hypothesis referred to as the alternative
hypothesis (and denoted by Ha) is then defined.
The hypothesis-testing procedure involves using data
from a sample to test two competing statements – one
denoted by Ho and the other by Ha.
