**Assessment of Electrical Power System Quality in Turkey**An evaluation of the electrical power system quality in Turkey was the subject of an article published in *Electrical Engineering* (March 2013). One measure of quality is the extent to which voltage fluctuations cause light flicker. The perception of light flicker \( x \), when the system operates at 380 kV, was measured periodically (in over 10-minute intervals). For transformers supplying heavy industry plants, the distribution of light flicker was determined to follow an approximate normal distribution with a mean (\( \mu \)) of 2.2% and a standard deviation (\( \sigma \)) of 0.5%.Suppose the light flicker perception surpasses 3.2%; in such a case, the transformer is shut down and the system reset. What is the likelihood of a transformer supplying a heavy industry plant needing to be shut down due to light flicker?---**Calculation**The probability that a transformer supplying a heavy industry plant has to be shut down due to light flicker is \[ \boxed{} \] (Round to four decimal places as needed).

For transformers supplying heavy industry plants, the light flicker distribution was found to follow…

Based on the data of air pollution in Los Angeles in 2019, the Environmental Protection Agency (EPA) decided to publish a new stricter regulation effective in January 2020 to reduce hydrocarbon pollution. EPA wants to evaluate whether the new regulation makes significant differences in reducing pollution. EPA collects data of monthly hydrocarbon pollution level as follows: Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 2019 7.3 6.0 5.4 5.9 3.9 5.7 6.9 7.6 6.3 5.8 5.1 5.9 2020 5.3 6.1 5.6 5.7 3.7 4.7 6.1 7.2 6.4 5.7 4.9 5.8

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. Presented is the data for beak heat loss, as a percent of total body heat loss from all sources, at various temperatures in degrees Celsius.

4. In a study, researchers wanted to measure the effect of alcohol on the hippocampal region, the portion of the brain responsible for long-term memory storage, in adolescents. The researchers randomly selected 21 adolescents with alcohol use disorders to determine whether the hippocampal volumes in the alcoholic adolescents were less than the normal volume of 9.02 cm°. An analysis of the sample data revealed that the hippocampal volume is approximately normal with no outliers and x = 8.14 cm ands = 0.8 cm³.
