On Schweser pg. 327 of book 1 - the solution to question 12 is C. In the calculation, it show that they multiply the z score by 0.1875. Could someone pls tell me where 0.1875 comes from? Thanks

That's a tricky one.

That no. is calculated like below and it's trial no. to find out which one comes under 95% of Confidence interval. i.e. +- 1.95

2.87 - 2.13 = 0.74 / 2 = 0.37 = .37 / 1.96 = 0.1887

We need to calculate with all answers to find out which one is with 95% interval.
