Let Z be a random variable following the standard normal distribution with mean µ = 0 and standard deviation σ = 1.
The 67th percentile of the distribution is the value z that separates the bottom 67% of the distribution from the top 100% - 67% = 33%. In terms of probability, we have
Pr[Z ≤ z] = 0.67
Use the inverse CDF for the normal distribution (or lookup z scores in a table) to find
z = ɸ⁻¹(0.67) ≈ 0.4399
where ɸ(z) is the CDF for the normal distribution.
Answer: A) he creates powerful visual images

9 is a square root because when u multiply 3×3=9
Thermotherapy refers to the type of treatment which is beneficial and most suitable for a client in the reduction of certain symptoms encountered such as muscle spasm.
<h3>What is Thermotherapy?</h3>
As the name implies involves the use of varying temperature as a form of therapy to certain medical conditions. This involves the application of a heating agent to reduce symptoms such as pain, spasm. The heat helps to loosen the blood vessels and ensure that there is increased blood flow to the affected part of the body system.
The high temperature will therefore loosen the muscles and ensure that they are much more relaxed. This method is suitable for promoting the healing process of most types of injuries and muscular issues encountered during our day to day activities.
