Question

If we conduct an experiment to see if there is a relationship between two variables, which of the following p-values could we expect if a relationship does indeed exist?

• a.)

  93%

• b.)

  50%

• c.)

  2%

• d.)

  6%

Given a 5% significance level, which of the following probability values would be considered not statistically significant?

• a.)

  0.459

• b.)

  0.023

• c.)

  0.011

• d.)

  0.995

Answer 1

Question 1.

We know that,

Relationship between variables is exit if the p-value is very low.

Here 2% and 6% are very low p-values.

Hence, option c) and d) are correct.

Question 2.

We know that,

The p-value is not statistically significant at 5% if it is greater than 0.05

Hence, 0.459 and 0.995 are greater than 0.05.

i.e., option a) and d) are correct.
