here is my question


Explanation: a) Hypotheses: Ho: B1 = 0 H1. P10 b) Type of test statistic: t Degrees of freedom = n - 2 = 35 - 2 = 33 c) Test statistic = Coefficient/SE = 0.35/0.26 = 1.346 d) This is a two tailed test. So, p - Value = 2*P(t(33) > 1.346) = 2*0.0937 = 0.187 e) NoThere may be an association between a country's birthrate and the life expectancy of its inhabitants. A report this past year, coming from a random sample of 27 countries, contained the following statistic: /= -0.40 for the two variables number of births per one thousand people and female life expectancy. Based on this information, test for a significant linear relationship between these two variables by doing a hypothesis test regarding the population correlation coefficient p . (Assume that the two variables have a bivariate normal distribution.) Use the 0.10 level of significance, and perform a two-tailed test. Then complete the parts below. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis . P H : 0 X H :0 (b) Determine the type of test statistic to use. (Choose one) 020 0+0 0
