Answer 1

From the following data calculate:
a. Coefficient of correlation
b. Standard deviation of Y
X=0.854Y; Y=0.89X; σx =3

Answer 2

Answer:

coefficient of correlation (r)= 0.822

Step-by-step explanation:

Coefficient of correlation :

The connection coefficient is a factual proportion of the strength of the connection between the overall developments of two factors. The qualities range between - 1.0 and 1.0. A determined number more prominent than 1.0 or not exactly - 1.0 intends that there was a mistake in the connection estimation. A relationship of - 1.0 shows an ideal negative connection, while a relationship of 1.0 shows an ideal positive connection. A connection of 0.0 shows no straight connection between the development of the two factors.

it can be used in finance and investing.

Coefficient of correlation = √YX  × Y

                                            = √  0.854 × 0.89

                                             = 0.822
