VladimirAG [237]

Answer:

Option C) 0.57

Step-by-step explanation:

We are given the following in the question:

Average, \mu_0 = 260 calories

Standard deviation, \sigma = 35 calories

\mu_1 = 240 calories.

We have to find the Cohen's d effective size.

Formula:

d = \bigg|\dfrac{\mu_1 - \mu_0}{\sigma}\bigg|\\\\d = \bigg|\dfrac{240-260}{35}\bigg|\\\\d = 0.57

Thus, the Cohen's d effective size is 0.57

Thus, the answer is

Option C) 0.57
