Answer:
It is an example of an empirical probability.
Step-by-step explanation:
The empirical probability, also called experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
Theoretical probability is probability that is determined on the basis of reasoning.
It is evident that the probability in the question was arrived at after the outcome of 14 days of whether Jerry Gergich spilled his lunch on himself or not.
It's an actual result of an experiment, hence the 12/14 = 0.86 = 86% that he spills his lunch on himself tomorrow.

Step-by-step explanation:
Answer:
We are 95% confident that the true proportion of adults overweight is between 0.644 and 0.672
Step-by-step explanation:
We can begin founding the estimated proportion of people overweight:
We need to find a critical value for the confidence level using the normal standard distribution. We know that 95% is the confidence level, then the significance level would be given by and . And the critical value would be given by:
The confidence interval for the true population proportion of interest is given by the following formula:
Replacing the data provided we got:
We are 95% confident that the true proportion of adults overweight is between 0.644 and 0.672
