Question

1. Classify the situation as stratified random sampling, systematic random sampling, or cluster sampling.

The situation is classified as (Click to select) systematic random/ stratified random/cluster sampling.

2. The mean amount of life insurance per household is $113,000. This distribution is positively skewed. The standard deviation of the population is $35,000. Use Appendix B.1 for the z-values.

     

(Click to select) Uniform/Normal/Not normal, the standard deviation is unknown/Unknown

What is the likelihood of selecting a sample with a mean of at least $117,000? (Round the final answer to 4 decimal places.)

What is the likelihood of selecting a sample with a mean of more than $107,000? (Round the final answer to 4 decimal places.)

Find the likelihood of selecting a sample with a mean of more than $107,000 but less than $117,000. (Round the final answer to 4 decimal places.)

  Sample mean:

1. Classify the situation as stratified random sampling, systematic random sampling, or cluster sampling.

  A college decided to survey its students to see how they felt about using a computer in all classes and how much extra tuition they would be willing to pay for the service.
