84.1% of adults have a cholesterol level less than 200 mg/dl (www. fnri. dost. gov. ph/). Suppose that the total cholesterol level is normally distributed. a. Determine the standard deviation of this distribution. b. What are the quartiles (the 25% and 75% percentiles) of this distribution

The answer to this question is c

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
