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?
