Explanation Approach: The normal curve is symmetric with respect to its mean. The total area under the curve is 1. Calculation: Given that z = − 0 .46 . To find the area above z = − 0 .46 , find the area between z = 0 and z = − 0 .46 . Due to symmetric property of the area to the right and left are equal. Thus, the area of z = − 0 .46 and z = 0 .46 are the same. So, find the value of z = 0 .46 . Find the z -score from the Table 14.19 for standard normal distribution given in the text. The corresponding value of z = 0 is 0. To find the corresponding value of z = 0 .46 , use the row for z = 0 .4 and the column labelled 0.06. The corresponding value of z = 0 .46 is 0

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…

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?…
