Detailed Question:
According to probability theory, we can determine a confidence interval around a sample statistic that will give us a range of error when comparing the sample statistic to the population statistic. We can also determine how much confidence we have in our range of error.
Explain this in more detail. What is a confidence interval and how does it relate to probability theory? Use an example to help explain your answer.
Write a program to simulate the random variables whose densities are given by the following, making a suitable bar graph of each and comparing the exact density with the bar graph.
Seeds. Information on a packet of seeds claims that the germination rate is 92%. What's the probability that more than 95% of the 160 seeds in the packet will germinate? Be sure to discuss your assumptions and check the conditions that support you..
Archaeopteryx is an extinct beast having feathers like a bird but teeth and a long bony tail like a reptile. Five fossil specimens have preserved both the femur and humerus bones. The measurements (in centimeters) for each bone are given below.
