Answer:
The Largest Number is 27.
Step-by-step explanation:
Range = Largest Number - Smallest Number
18 = Largest Number - 9
Rearrange the formula to find the Largest Number:
Largest Number = Range + Smallest Number
Largest Number = 18 + 9
Largest Number = 27
You can check this by putting it into the original formula:
Range = Largest Number - Smallest Number
18 = 27 - 9
Answer:
estimated sample mean X is 14.7 minutes
sample standard deviation is ≈ 0.59 minutes.
Step-by-step explanation:
Let X be the mean delivery time for a random sample of 40 orders at this restaurant, then
X can be estimated as 14.7 minutes (mean delivery time for all food orders at a fast-food restaurant during the lunch hour)
Let s be the standard deviation of delivery time for a random sample of 40 orders at this restaurant, then
≈ 0.59 where
- 3.7 is the standard deviation of the delivery times for all food orders at a fast-food restaurant during the lunch hour
- 40 is the sample size
