<span>This study is a randomized control trial (RCT). In an RCT, participants are randomized into one of two groups - an intervention group or a control group. The intervention group receives the treatment of interest to the researchers (in this case, computers and educational software) while the control group does not. This will allow the researchers to examine the effect of the intervention (computers and educational software) on achievement tests scores.</span>

North Around, Inc. stock is expected to return 22 percent in a boom, 13 percent in a normal economy, and −15 percent in a recess
almond37 [142]

Answer:

4.53%

Explanation:

Data provided in the question:

Expected return = ∑ (Return × probability)

Thus,

Expected return = (0.06 × 22) + (0.92 × 13) + (0.02 × (-15))

= 12.98%

Now,

Probability       Return        Probability × (Return-Expected Return)²

0.06                  22                   0.06 × (22% - 12.98%)² = 4.8816

0.92                  13                    0.92 × (13% - 12.98%)² = 0.000368

0.02                  -15                   0.02 × (-15% - 12.98%)² = 5.657608

========================================================

                                                                            Total = 20.5396%

Standard deviation = \sqrt{\frac{\text{Total probability}\times(\text{Return-Expected Return})^2}{\text{Total probability}}

= √(20.5396)

= 4.53%
