The output from a statistical software package indicates that the mean and standard deviation of a data set consisting of 100 measurements are $2100 and $500, respectively. And it is also known that the distribution is symmetric and mound shaped (in other words, the empirical rule may be applied to this data set). a. What can be said about the number of measurements between $1100 and $3100? Approximately (?) of the measurements are between $1100 and $3100. b. What can be said about the number of measurements between $600 and $3600? Approximately (?) of the measurements are between $600 and $3600. c. What can be said about the number of measurements between $1600 and $2600? Approximately (?)of the measurements are between $1600 and $2600.
