ANSWER:Solution:
Step 1 of 3:
The output from a statistical software package indicates that the mean and standard deviation of a data set consisting of 200 measurements are $1,500 and $300, respectively.
- We have to find the units of measurements of the variable of interest, and the type of data.
- We have to find the number of measurements between $900 and $2,100, between $600 and $2,400, between $1,500 and $2,100.
