Question

Joanna, a machine learning engineer is studying what programming languages are the most effective to help systems learn from data. Based on previous research, more than 50% of machine learning involves the use of Python, a programming language. She suspects this percent has increased in recent years. In the process of hypothesis testing, what set value will allow Joanna to make a conclusion about whether her sample proportion is "different enough" than the claimed population proportion?a. p-value

b. test statisticc. significance leveld. null hypothesis

Answer 1

Option A

Explanation:

The p-value will help Joanna in coming to a conclusion about her hypothesis. The p-value derived from the test statistics calculated gives an immediate accurate summary of inference information (using significance levels, confidence intervals etc) for the parameter of interest.

It is used as an alternative to rejection points; a smaller p value means there is stronger evidence leading to the rejection of the null hypothesis and vice versa.
