Exercise 4

Exercise 4: Uncertainty about probability of 80% decline in 20 years, but relative certainty about 80% decline within 50 years

Type 'Lab3' at the prompt.
Pick dataset 7.
Pick 80% decline in 50 years.

Questions:

1. Any type of confidence interval (frequentist) or credible interval (Bayesian) we might put on mu is going to include 0 (not declining). Similarly the intervals for probability of 80% decline in 50 years will be 0 to 1, indicating we can't say much about the absolute probability of 80% decline in 50 years. Do you think the reasonable conclusion here is that we can't say anything about whether declines are plausible in this population?
