Choose one country that you might like to visit. Select a duration for your trip between two and six weeks, and then choose a number of participants between 5 and 10 people. Suppose one goal of your group is to speak to every adult citizen in the country.

According to the National Center for Health Statistics, the mean height of an American male is 69.3 inches and the mean height of an American female is 63.8 inches. The standard deviation for both genders is 2.7 inches.According to Chebyshev’s Theorem 75% of the data for your gender lies between what two heights?If height is assumed to be normal, what percentage of the data lies between those same two heights?Look in the Guided Worksheets on page 49 for more information. A Microsoft Excel spreadsheet is required for this DQ. Chapter from book attachedNote from Professor:Dear class,1. Read example 13 on page 03-25 to review z score and SD.2. Read example 14 on page 03-30 to under the SD of a normal distribution.3. Find page 49 in the guided worksheets under the Course Materials to understand "Chebyschev’s Theorem." : For any data set at least 75% of the data values are within 2 standard deviations of the mean and at least 89% are within 3 SD’s.
