Explanation:
To find the percentage of cars averaged less than 62 mph calculate the corresponding z-score and use a standard normal cumulative probability table
<u>1. Z-score</u>
![Z-score=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=Z-score%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
- x is the specific value of the random variable: 62mph
- μ is the mean of the population: 65mph
- σ is the standard deviation of the population: 5mph
Substitute and calculate
![Z-score=\dfrac{62-65}{5}=-0.600](https://tex.z-dn.net/?f=Z-score%3D%5Cdfrac%7B62-65%7D%7B5%7D%3D-0.600)
<u>2. Use of the table.</u>
The percentage of cars that averaged less than 62mph is given by the area under the curve to the left of z = -0.600.
From a standard normal cumulative probability table, the probability of z being less than -0.600 (which is equal to the probability of z being greater than 0.600) is 0.2743, which is 27.43%.
Thus, the conclusion is that 27.43% of the cars averaged less than 62mph.
The document shows a personal allowances worksheet. The document asks about dependents because the number can lower overall taxes
For better understanding let's explain what the personal allowance worksheet means
- The Personal Allowances Worksheet is commonly known as a worksheet that is often used for getting to know more about the number of deductions or simply say personal allowance that an individual can claim. It is stated that more allowances you claim, the lesser the tax that is withhold from an individual's paycheck.
From the above we can therefore say the answer, The document shows a personal allowances worksheet. The document asks about dependents because the number can lower overall taxes, is correct
