According to the travel blog, an economy class meal costs about 4 dollars on an airline. This given amount is called a statistic. 3. A measure that is computed to describe the characteristics of an entire population i called a parameter. X-H 4. The formula is used to gain information about an individual data value when the variable is normally distributed. 5. Every 30th person was selected from the list of registered voters. The appropriate sampling method used is random sampling. 6. Five taxpayers were randomly chosen from each barangay in a certain district. The sampling method used is stratified sampling. 7.
