I’m confused by the formula on question 1. I can’t find this working in my Kaplan book or on the Opentuition lectures.
Would it be possible to explain or point me in the direction of an explanation. I understand the consempt but just want to be able to remember the formula for the exam

Question 3 appears to be marking incorrectly.
It accepts answers between 7 and 7.1
The working it gives is :
std dev is sqrt of 9 = 3
49% z value is 2.33
VAR = 2.33 x 3
The answer, therefore, is 6.99 NOT between 7 and 7.1
