Explanation / Answer

Solution:- Given that x1 = 42, X2 = 46
?1 = 12, ?2 = 16
n1 = 35, n2 = 36

90% confidence interval for Z = 1.645

90% confidence interval difference in population means
: (x1 - x2) +/- 1.645*sqrt((?1^2/n1) + (?2^2/n2))

= (42 - 46) +/- 1.645*sqrt((12^2/35) + (16^2/36))

= -9.51 , 1.51
