Answer to Problem 1CRP

The measures of variation that indicate spread about the mean is standard deviation and variance.

Explanation of Solution

The measures of variation describe the spread of the data. The standard deviation and variance is used to describe the spread of the data around the mean. The standard deviation is based on the difference between each data value and the mean of the data. Moreover, the average spread of the data around the mean is provided by the standard deviation. Hence, the measures of variation indicated spread about the mean is standard deviation and variance.

To determine

Identify the graphic display that shows the median and data spread about the median.

Answer to Problem 1CRP

The graphic display that shows the median and data spread about the median is box-and-whisker plot.

Explanation of Solution

The spread of the data around the median is identified using box-and-whisker plot. Moreover, the box-and-whisker is created using the five number summary. That is, minimum, first quartile, median, third quartile, and maximum. Hence, the graphic display that shows the median and data spread about the median is box-and-whisker plot.

(c) Because logistic regression predicts probabilities of outcomes, observations used to build a logistic regression model need not be independent. A. false: all observations must be independent B. true C. false: only observations with the same outcome need to be independent I ANSWERED: A. false: all observations must be independent.  (This was marked wrong but I have no idea why. Isn't this a basic assumption of logistic regression)

Spam 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. What is the predicted probability that this message is spam?…
