please help on both 1.) We learned in section 6.1 that the Empirical Rule (a.k.a 68-95-99.7 rule) is a good estimate of probability within a specific number of standard deviations from the mean for any normal distribution. We know that this rule only provides a good estimate and that it is not very precise. With use of the Normalcdf function in our calculator, we can find exact values. For example, when using the Empirical Rule 95% is expected to be...

Use the Empirical Rule. (Do not use technology. Technology will give a slightly different answer.) Draw a sketch of the normal distribution and label the mean and 1, 2, and 3 standard devitons above and below the mean with computed values. Assume that the weight of 1-year-old girls in the USA is normally distributed with Mean = 9.5 kg, Standard Deviation = 1.1 kg. What percentage of the data is more than 12.8 kg?

Problem 6 In some state the mean ACT score in Mathematics is μACT = 19 and the standard deviation is σ ACT = 6, while the mean SAT score in Mathematics is AsAT = 480 and the standard deviation is AT 90. Suppose that the ACT scores and the SAT scores have a normal distribution. Terence gets a score of 17 on the Mathematics portion of the ACT and Philip gets a score of 356 on the Mathematics portion of...

The Normal Distribution, also called the Gaussian Distribution, is a representation of the distribution of many different types of data, especially when considering large amounts of data. Some examples of data that are normally distributed are IQ scores, heights, blood pressure measurements and GPAs. The empirical rule, along with the Normal Distribution provides information about the data that is easy to calculate. Follow this link to understand the empirical rule and see an example regarding IQ scores: http://cfcc.edu/faculty/cmoore/Empirical_Rule.htm For Discussion...
