D Question 17 5 pts Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your finding to state whether or not the given r represents a significant linear correlation. Use a significance level of 0.05. r = 0.543, n = 25 Critical values: r = +0.396, no significant linear correlation O Critical values: r = +0.487, significant linear correlation O Critical values: r = +0.396, significant linear correlation Critical values: r = 10.487, no significant linear correlation Question 18 5 pts A laboratory tested 82 chicken eggs and found that the mean amount of cholesterol was 228 milligrams with o = 19.0 milligrams. Construct a 95% confidence interval for the true mean cholesterol content, u, of all such eggs. 223 mg
