We reject the null hypothesis of the given sample data below.

A type of statistical hypothesis known as a "null hypothesis" makes the case that a given set of observations does not have any statistical significance. Using sample data, hypothesis testing is used to determine a hypothesis's credibility. It is represented as H0, and it is sometimes referred to as the "null."

it is given that,

P value=0.0045

Thus, alpha = 0.02

At the point when P esteem is not exactly or equivalent to the importance level, then reject the null hypothesis.

Here p esteem is not as much as the importance level then reject the null hypothesis H0.
