18.42 this wine stinks. how sensitive are the untrained
noses of students? exercise 16.27 (page 390) gives the
lowest levels of dimethyl sulfide (dms) that 10 students
could detect. you want to estimate the mean dms odor
threshold among all students and you would be satis-
fied to estimate the mean to within 0.1 with 99%
confidence. the standard deviation of the odor thresh-
old for untrained noses is known to be o = 7 micro-
grams per liter of wine. how large an srs of untrained
students do you need?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
