H1: βj≠ 0, where βj is a regression coefficient associated with an explanatory variable, represents a one-sided alternative hypothesis.Question 3Select one:TrueFalse

If the calculated value of the t statistic is greater than the critical value – the null hypothesis – H0 is rejected in favour of the alternative hypothesis, H1.Question 4Select one:TrueFalse

A significance test of H: B = 0 against the two-sided alternative H: B # 0, where B = the slope of the population least-squares regression line for predicting Ethereum price from Bitcoin price, was conducted at the 5% significance level. Which of the following gives the correct decision for the significance test and the possible error that could result from this decision? (A) Fail to reject the null hypothesis; Type I error (B) Fail to reject the null hypothesis; Type II error (C) Reject the null hypothesis; Type I error (D) Reject the null hypothesis; Type II error (E) Reject the null hypothesis; either Type I error or Type Il error is possible
