Textbook Question
Chapter 1, Problem 1CR
Terminology If a numerical measure describes an aspect of a sample, is it a statistic or a parameter?
Expert Solution & Answer
To determine
Whether the statement is a statistic or parameter.
Answer to Problem 1CR
Solution: A numerical measure describing an aspect of a sample is a statistic.
Explanation of Solution
A sample statistic is a numerical measure that describes an aspect of a sample and a population parameter is a numerical measure that describes an aspect of a population. Parameter is drawn from the measurements of the units of population and on the other hand, the statistic is drawn from the measurements of the elements of the sample.

- Business discussarrow_forwardSpam filters are built on principles similar to those used in logistic regression. We fit a probability that each message is spam or not spam. We have several variables for each email. Here are a few: to_multiple=1 if there are multiple recipients, winner=1 if the word 'winner' appears in the subject line, format=1 if the email is poorly formatted, re_subj=1 if "re" appears in the subject line. A logistic model was fit to a dataset with the following output: Estimate SE Z Pr(>|Z|) (Intercept) -0.8161 0.086 -9.4895 0 to_multiple -2.5651 0.3052 -8.4047 0 winner 1.5801 0.3156 5.0067 0 format -0.1528 0.1136 -1.3451 0.1786 re_subj -2.8401 0.363 -7.824 0 (a) Write down the model using the coefficients from the model fit.log_odds(spam) = -0.8161 + -2.5651 + to_multiple + 1.5801 winner + -0.1528 format + -2.8401 re_subj(b) Suppose we have an observation where to_multiple=0, winner=1, format=0, and re_subj=0.
