A. Use your calculator. B Since it follows the standard normal distribution, the standard deviation(s) equals to one. S= variance = 1. A. Z= (42-50)/10=-0.8. Enter table A under Z=-0.8. The table entry is 0.2119. This is the area to the left of –0.8. Because the total area under the curve is 1, the area lying to the right of –0.8 is 1-0 ...

Standard Deviation “Z” is the number you can look up in the border of the Normal Distribution Table in the back of your textbook. You then read the probability out of the body of the table. Suppose you boss wants the project done in 25 weeks. You now have all the data you need to calculate Z. The Due Date is 25, the mean is 20.5, and the ...

So, we can use the z table. c. T. Since the population has a normal distribution, the sampling distribution of is also normal. So, we can use the z table. d. F. The distribution is not Normal because the 68,95,99.7% rule does not apply. The sample size is quite small (1), so the CLT does not apply. So, we can’t use the z table. e. F.

Calculate the z-scores corresponding to both 12.1 and 12.76, and find the Standard Normal Probabilities for each, using a calculator or the Standard Normal Probabilities Table. Explain how you would use those values to determine the probability a bag chosen at random will contain between 12.1 and 12.76 oz.

In fact, for any number (or fraction) of standard deviations, we know exactly what percent of the data fall within that number of standard deviations of the mean. For example, consider the normal curve percentages in the table below. Given a number z of standard deviations, the table gives the percent of data values between the mean ( and ((z(.

For a standard normal variate z, the normal distribution has mean zero and standard deviation one with pdf ... But this difficulty we can manage using standard values from the table 5 of Normal distribution at page # 423 or using our calculator. Look at example 3. ...

A normal distribution of scores has a standard deviation of 10. Find the z-scores corresponding to each of the following values: A score that is 20 points above the mean. z=2. A score that is 10 points below the mean. z=-1. A score that is 15 points above the mean z=1.5. A score that is 30 points below the mean. z…
