Lily replicates an experiment that found that the number of calories in a particular food is 50 kcal. she obtained data from five trials: 50 kcal, 72 kcal, 50 kcal, 12 kcal, and 50 kcal.
which best describes her data results?

results is describe as accurate

Explanation:

given data:

five trial value is given as

50 kcal, 72 kcal, 50 kcal, 12 kcal, 50 kcal

from information in the given question number of calories found to be 50 kcal

we need to find out the best  results from data:

so we know that

mean = sum of value divide by number of value

mean  = 46.8  which is round of to 47

Deviation from original value is called as error. so error is calculated as

which is less  hence is results is describe as accurate

the answer is b ) square root of 5

c
