The Importance of Vehicle Safety in the Contemporary Period Research Paper

The Importance of Vehicle Safety in the Contemporary Period - Research Paper Example Drunk driving is forbidden in most of the countries across the world owing to its immense potential to cause harm not only to the drunk driver but also to the other drivers and passers-by. When an individual is drunk, he/she loses the consciousness level that is required to drive prudently. Overcome with emotions and sleepiness, the individual takes sharp turns and drives at a very fast speed. Many people tend to drive after drinking thinking that they are too trained to be caught in an accident. A vast majority of the drunk drivers are quite expert at driving, but when the individual is not fully conscious, the driving skill becomes a secondary factor. What the driver primarily requires is control over the senses. A drunk driver does not even realize when he/she sped up more than necessary, and in the very moment, was caught in the accident. Wearing a seat belt seems a formality to a lot of drivers and many consider it too simple a protective measure to be efficient, though it is a fundamental necessity of driving. The seat belt is a shock absorber. It holds the driver back and keeps the head from smashing against the front mirror or the steering in the instant when the car suddenly strikes against something or is caught in an accident. Whenever a car suddenly stops, the lower part of the body stops with it while the upper part keeps moving at the same speed due to inertia. Thus, drivers that do not wear the seat belt get their heads crashed while the lower part of the body remains intact. But since the head is wounded, it means the brain is wounded. The human brain is amongst the most sensitive body organs and is of prime importance since it controls the body functions. Any damage to the brain cannot be sustained by the body. This is the reason why a vast majority of the drivers getting wounds in the head died at the sp ot. Thus, wearing a safety belt while driving is a must.

Maths and Excel exercise - Essay Example The horizontal dotted line indicates that the blue curve and the green curve have the same maximum. The vertical dotted lines indicate the maxima for the three curves, respectively. g) The weight of the heads of household appears to be normally distributed. Wages however are extremely skewed, resulting in many households with low wages and a few with high wages. The education level is a symmetric, discrete distribution, with both highly educated and less educated heads of households being rare. Since weight is the only symmetric distributed variable in the table, only in its case are the sample mean and median close to each other. Another indication that weight is indeed normally distributed is the proximity of the actual percentages of weights falling within the three given intervals to the empirical percentages. This is because the empirical percentages are calculated assuming normality of the data. An interesting observation is that the size of the 95% confidence interval for clothing and recreational expenses is actually much higher than that of more basic expenses such as food and housing. It is also interesting to note that clothing and recreational expen ses are more tightly correlated with net income than food and household expense are, as indicated by the marginally higher correlation coefficient of TOTEXP2 with FINC than TOTEXP1 with FINC. ... TOTEXP2 10.82 109.38 Note: 95% Confidence Interval has been calculated for the left tail, since all 3 variables show skewed distributions. e) Correlation coefficient r = 0.9927 Correlation coefficient r = 0.9979 f) The regression equation for TOTEXP1 Vs FINC is y = .59x + 1.5, while the regression equation for TOTEXP2 Vs FINC is y = .16x + .088 g) The weight of the heads of household appears to be normally distributed.

One possible interpretation is that spending on less basic needs is more constrained by income than spending on more basic needs
