Between the years of 1947 and 1956, earthenware jars containing what are known as the dead sea scrolls were found in caves along the coast of
jerusalem in the dead sea. upon radiometric testing, it was found that the scrolls were wrapped in material that contained about 79 percent of
the original carbon-14. archeologists estimated that the scrolls are about 1,900 years old. are they right?
question 1
using the half-life of carbon-14 (5,730 years), prove or disprove this estimate age. describe how you are testing this hypothesis.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
