In this week's experiment, we will examine the technique of random sampling as a tool for the estimation of large populations.

After reading the background material, can you think of any ecological experiments in which the random sampling technique could be helpful? Post your ideas, and do a bit of research to see if any scientists may have actually used this idea as well.

The steps involved in reaching the solution.

The solution.

1 The Lind text lists 5 reasons for sampling. List them and give an example of each type.
2 Using the descriptive statistics data determined during Week One's weekly problem discussion, the mean for EI followed a standard distribution with a mean of 132.83 and a standard deviation of 15.68. If we selected another random sample of 50 participants, Note for #2: All the information you need to solve the question is contained in the question.

a What is the likelihood of selecting a sample with a mean EI score of at least 134?
b What is the likelihood of selecting a sample with a mean EI score of more than 128?
c What is the likelihood of selecting a sample with a mean EI score of more than 128 but less than 134?
Please show likelihood as a decimal with two decimal places.
3 The mean Verbal SAT score for Division I student-athletes is 523 with a standard deviation of 103. If you select a random sample of 60 of these students, what is the probability the mean is below 300? Above 450?
