Solution :
Given that ,
A two-sided confidence interval is
= 0.10
/ 2 = 0.10 / 2 = 0.05
Z/2
= Z 0.05 = 1.645
Critical value = 1.645

please help with question 4
degrees of freedom for either the numerator or denominator of F, use the closest smaller number. For instance, if the degrees of freedom for the denominator were df, 23 you would use the critical value for df = 20 (2,3) 4. Chapter 10, Problem 10.10 If the degrees of freedom for I do not appear in Table A.2 use the closest smaller degrees of freedom to determine the critical value of t. For instance, if...
