Answer:
1800 mi
Step-by-step explanation:
Recall that (distance) = (rate)(time).
Here, (distance) = (200 mi/hr)(8.5 hr) = 1800 mi
Answer: The mean increases.
Step-by-step explanation:
The value of 0.9 mg/L is very low compared to a means of 7.6 mg/L with a standard deviation of 2.1 mg/L. It seems as though it is an outlier that is suffiently different from the others, and probably should be dropped from the data set. That would do 2 things: 1) the stabdard deviation will likely decrease, indicating a more confident data set, and 2) the mean vitamin C level will increase.
The answer is: Yes, all conditions for inference are met.
