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.)
