three drivers competed in the same fifteen drag races. the mean and standard

deviation for the race times of each of the drivers are given.

driver a had a mean race time of 4.01 seconds and a standard deviation of 0.05

seconds

driver b had a mean race time of 3.96 seconds and a standard deviation of 0.12

seconds

driver c had a mean race time of 3.99 seconds and a standard deviation of 0.19

seconds.

a.

which driver had the fastest typical race time?

b.

which driver's race times were the most variable?

c.

which driver do you predict will win the next drag race? support your

prediction using the inean and standard deviation.

i know the answer is 3

step-by-step explanation:

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.

hope this : )
