Q2. 2. What is Hypothesis testing and its types ?
Ans. 
Hypothesis testing is a statistical method to test a hypothesis about a population parameter.
• It involves formulating a null hypothesis and an alternative hypothesis.

• The null hypothesis assumes that there is no significant difference between the sample and population.

• The alternative hypothesis assumes that there is a significant difference between the sample and population.

• Types of hypothesis testing include one-tailed ...read more
