What does deviation, or "deviate" mean? How can it help you remember the definition of *mean absolute deviation"? Deviate means to depart from, or go away. This can help remember that mean absolute deviations is the average distance away. STEPS TO To find the mean absolute deviation for a set of data, follow these steps: 1. Find the of the data set CALCULATE MAD. 2. Find the from each data point and the mean 3. Find the of those distances Practice folwing the steps to calculate the mean absolute deviation in the problem below. 1.

Suppose that a random sample of adult males has a sample mean heart mass of x¯=310.1 grams, with a sample standard deviation of s=6.6 grams. Since adult male heart masses are generally symmetric and bell-shaped, we can apply the Empirical Rule. Between what two masses do approximately 68% of the data occur? Round your answer to the nearest tenth. Approximately $68\%$68% of the men's heart masses are between _____ grams and ______ grams.

Hi. Can i get some help with the question below please. Calculation steps and explanations. Boys of a certain age are known to have a mean weight of µ = 85 pounds. A complaint is made that the boys living in a municipal children’s home are underfed. As one bit of evidence, n = 25 boys (of the same age) are weighed and found to have a mean weight of x¯ = 80.94 pounds. It is known that the population standard deviation σ is 11.6 pounds (the unrealistic part of this example!). Based on the available data,what should be concluded concerning the complaint?

Calcium levels in people are normally distributed with a mean of 9.7 mgdL and a standard deviation of 0.5 mgdL . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
