For a two tailed test using the normal distribution,a significance level of 0.10 would have a critical value of?

For a two-tailed test with a significance level of 0.10, the critical value would be ±1.645. This is because the critical values for a two-tailed test at a significance level of 0.10 are z = -1.645 and z = 1.645. These values represent the cutoff points for rejecting the null hypothesis in favor of the alternative hypothesis.
