1.In testing the statistical hypothesis, which of the following statement(s) is TRUE?In testing H0:μ=μ0, H1:μ≠μ0, the critical region is two sided.For testing H0:μ=μ0, H1:μ>μ0, we reject H0 for high values of the sample mean The level of significance is the probability of type II error.The critical region is the values of the test statistic for which we reject the null hypothesis.The p-value measures the probability that the null hypothesis is true.
