Answer:
B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.
In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.
Answer:
0.166 = 16%
Step-by-step explanation:
There are three different options to pick in the bag, so the probability of getting a nickel first is 1/3, and then the probability of getting a penny without replacing the nickel is 1/2, as there will be only 2 options remaining after the nickel was picked.
So the final probability is the product of these probabilities:
P = (1/3) * (1/2) = 1/6 = 0.166 = 16%
Let number of magazines=x and number of books =y:
3.95x+8.95y=47.65
