Asample of n = 25 individuals is selected from a population with µ = 60 and sigma = 10 and a treatment is administered to the sample. after treatment, the sample mean is m = 63. what is the value of cohen's d for this sample?

The information regarding the sampling shows that the value of cohen's d for this sample is 0.3.

From the information given, the sample of n = 25 individuals is selected from a population with µ = 60 and sigma = 10 and a treatment is administered to the sample. after treatment, and the sample mean is m = 63.

Therefore, the value of cohen's d for this sample will be:

= (M - µ) / 10

= (63 - 60) / 10

= 0.3

In conclusion, the correct option is 0.3.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
