Show your work by using the formula.**Empirical Rule****c) Suppose that the data are sampled from a normally distributed population. Using the empirical rule, what percentage of the data should we expect to be within interval one?**---**Explanation:**1. **Interval Calculations:** - Interval 1 represents the range within one standard deviation from the mean. - Interval 2 represents the range within two standard deviations from the mean. - Interval 3 represents the range within three standard deviations from the mean.2. **Chebychev's Rule:** - This rule provides a minimum percentage of observations that fall within a given number of standard deviations from the mean, applicable to any distribution. - The formula for Chebychev's Inequality is: \( 1 - \frac{1}{k^2} \)3. **Empirical Rule:** - Applicable for normally distributed data, this rule states: - Approximately 68% of data lies within one standard deviation. - Approximately 95% lies within two standard deviations. - Approximately 99.7% lies within three standard deviations.This question requires students to apply statistical concepts, such as interval notation, Chebychev's Inequality, and the Empirical Rule, to estimate data distribution in a sample set.

An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 4 IQ points of the true mean. Assume that σ=10 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.

Which of the following is NOT an assumption of the χ2 test? It is a nonparametric test. It is appropriate only for ordinal data. The frequency in each cell should be at least 5. The sample should be randomly selected.
Let a population consist of the values 11 cigarettes, 12 cigarettes, and 22 cigarettes smoked in a day. Show that when samples of size 2 are randomly selected with replacement, the samples have mean absolute deviations that do not center about the value of the mean absolute deviation of the population. What does this indicate about a sample mean absolute deviation being used as an estimator of the mean absolute deviation of a population? Calculate the mean absolute deviation for each possible sample of size 2 from the population.
