Answer:
C. -0.68427
Step-by-step explanation:
Enter the data into a graphing calculator.
First decide which is the independent and which is the dependent variable. Since the value of the stock depends on the day, value will be dependent and day will be independent.
This means that the days will be entered into the first list and the values will be entered into the second list.
Entering these and running the linear regression, we find the r-value to be -0.68427
.
A. The percent of cherries that are produced in the state is calculated by dividing the number of cherries produced in the state by the total number of cherries and multiplying the quotient by 100%.
r = (74 / 100) x 100% = 74%
B. The percent of cherries not produced in the state is equal to difference of the 100 and the answer in letter A. This is shown below.
s = 100% - 74%
s = 26%.
