Question

"Henri has calculated a z-test statistic of -2.73. What is the p-value of the test statistic? Answer choices are rounded to the thousandths place."

Answer 1

Answer:

0.003

Step-by-step explanation:

P-value = The value of probability.

P value can be defined are the probability of a given test statistic ( which could be z score, t score, f score) that is can be less than, equal to or greater than a given null hypothesis.

In the above question, the test statistic we are given = z score.

z score = -2.73

To find the P- value, we can make use of a z table for normal distribution.

Hence, P(z = -2.73) = 0.0031667

Approximately to the nearest thousandth = 0.003
