Suppose X∼N(16.5,2), and x=18.5. Find and interpret the z-score of the standardized normal random variable. Provide your answer below:

The z-score when x=18.5 is :
. The mean is :

This z-score tells you that x=18.5 is
standard deviation(s) to the right of the mean.

i dont know the answer sorry

Step-by-step explanation:

7

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
