Question 2.6 Run the same analyses on the small and large samples that you previously ran on the full dataset and on the convenience sample. Compare the accuracy of the estimates of the population statistics that we get from the convenience sample, the small simple random sample, and the large simple random sample. (Just notice this for yourself -- the autograder will check your sample statistics but will not validate whatever you do to compare.)

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e β0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some βreal-worldβ examples and uses of cobalt-60
