Question

For a confidence level of 99%, find the critical value

Answer 1

The critical value for a confidence level of 99% can be found using the Z-score table or by using a statistical calculator. For a two-tailed test, the critical value is typically ±2.576.

This means that when conducting a hypothesis test with a confidence level of 99%, any test statistic beyond ±2.576 standard deviations from the mean would fall in the critical region, leading to rejection of the null hypothesis.
