Answer:
0.9113
Step-by-step explanation:
Given :
Sample standard deviation of Stock X = 4.665
Sample standard deviation of Stock Y = 8.427
Sample Covariance = 35.826
The Correlation Coefficient, R is related to sample covariance and standard deviation using the formular :
R = Covariance(X, Y) / (SD(X) * (SD(Y))
R = 35.826 / (4.665 * 8.427)
R = 35.826 / 39.311955
R = 0.9113
Hence, correlation Coefficient, R = 0.9113 which depicts a strong positive relationship.
Part A
We know that √x = 3
Squaring both sides
x = 3²
⇒ x = 9
Hence, the value of x or the minimum value of x is 9
Part B
(*y²) ÷ (0.4*) = (*y²) *
⇒ (*y²) ÷ (0.4*) = *yx
If you would like to know how many students will be allowed to attend recess on Friday, you can calculate this using the following steps:
7/8 of 24 students = 7/8 * 24 = 7 * 3 = 21 students
Result: 21 students will be allowed to attend recess on Friday.
In a(n) <u>reversal</u> design, two or more treatments are alternated relatively quickly on a regular schedule.
Reversal designs are used to observe the impact of a remedy on the conduct of a single player. The participant is observed time and again previous to remedy to establish a baseline stage of behavior.
One ought to not use a reversal layout with behaviors that aren't reversible. For instance, if you train a person to fish, that man or woman is not probable to forget about how to fish, making a reversal design a negative preference for evaluating your fishing intervention.
Reversal layout: reversing among remedies (e.g., baseline, treatment, NCR, treatment, NCR, remedy, and many others.) Withdrawal design: reversing among treatment and no treatment (e.g., baseline, remedy, baseline, treatment, etc.)
