Answer:
When the p-value obtained from a hypothesis test is very low (close to zero), it suggests that the results are statistically significant. In the context of your analysis, a p-value of 0.0 indicates strong evidence against the null hypothesis, which typically means that you can reject the null hypothesis.
Thus, based on the extremely low p-value obtained in your test of hypothesis, the interpretation of the result would be:
b. Lack of experience is really a cause of repeat calls.
This means that there is strong evidence to suggest that lack of experience is indeed a significant factor contributing to repeat calls.
