In Piaget's epistemology, cognitive schemas are acquired and formed through a process of internalization conceived of as a functional incorporation of the regular structure of actions into the memory (Piaget 1954). Schemas are higher-level cognitive units that are acquired through slow learning.

The proportion of students that got the recommended amount of sleep is 0.179.
<h3>What is a proportion?</h3>
A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
<h3>How to calculate proportion of students that got the recommended amount of sleep?</h3>
Since the total number of students in this class is 28, we would develop an expression to relate the number of students that sleep at least for 5 hours per night:
Proportion = 5/28
Proportion = 0.179.

Answer: Risk free rate = 1.9%
Explanation:
The Capital Asset Pricing Model allows for the calculation of the required return using the market return, beta and risk free rate.
Required return = Risk free rate + Beta * ( Market return - Risk free rate)
First find the market rate. Stock Y is uniquely positioned to help with that:
12.4% = Risk free rate + 1.0 * (Market return - Risk free rate)
12.4% = rf + Market return - rf
Market return = 12.4%
Apply this to the formula using Stock Z:
8.2% = rf + 0.6 * (12.4% - rf)
8.2% = rf + 7.44% - 0.6rf
rf - 0.6rf = 8.2% - 7.44%
0.4rf = 0.76%
rf = 0.76% / 0.4
Risk free rate = 1.9%
