Naddika [18.5K]

Answer:

$7,925.53

Step-by-step explanation:

We'll have to use the compound interest formula: A = P(1 + r/n)ⁿˣ

A = final amount (?)

P = starting amount (5700)

r = rate

n = times applied (12 since its monthly and there 12 months in a year)

x = years (12)

A = 5700(1 + 0.0275/12)¹⁴⁴

A = 7925.525498629932

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
