Discuss the concept of the null hypothesis and its use in data analysis.

Null hypothesis may be defined as the any type of assumption in which the observed difference between two sample in the statistical population is accidental. Null hypothesis is used in the field of genetics as well.

If one accepts the null hypothesis this means that there is no significant differences between the observed values and the expected values of the experiment. The rejection of null hypothesis explains that there may be significant difference between the expected value and observed value.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite
