The file P14_01.xlsx contains data on 100 consumers who drink beer. Some of them prefer light beer, and others prefer regular beer. A major beer producer believes that the following variables might be useful in discriminating between these two groups: gender, marital status, annual income level, and age. a. Use logistic regression to classify the consumers on the basis of these explanatory variables. How successful is it? Which variables appear to be most important in the classification? b. Consider a new customer: Male, Married, Income 42,000, Age 47. Use the logistic regression equation to estimate the probability that this customer prefers Regular. How would you classify this person?

Suppose a social psychologist sets out to see whether having children is related to relationship longevity. He decides to measure relationship satisfaction in a group of couples with children and a group of childless couples. He chooses the Marital Satisfaction Inventory because it refers to “partner” and “relationship” rather than “spouse” and “marriage,” which makes it useful for research with both traditional and nontraditional couples. Higher scores on the Marital Satisfaction Inventory indicate greater relationship satisfaction. The psychologist administers the Marital Satisfaction Inventory to 58 couples—30 are couples with children and 28 are childless couples. He wants to calculate the correlation between a couple’s relationship satisfaction and whether they have children. Which of the following types of correlations would be most appropriate for the psychologist to use?

Paraphrase this one. Analyze and elaborate in 120 words. Predictive analytics involves a statistical approach called regression, which helps us uncover connections between different factors. This technique is valuable for spotting trends within extensive sets of information and figuring out how various inputs relate to each other. It shines brightest when dealing with continuous information that follows an established pattern. Regression frequently comes into play when we want to understand the impact of one or more independent factors on another. For instance, it aids in grasping the effect of raising prices on product sales. This tool holds the key to unraveling hidden insights in data that might otherwise remain unnoticed.

A pharmacist has been monitoring sales of a certain over-the-counter pain reliever. Daily sales duringthe last 15 days wereDay: 1 2 3 4 5 6 7 8 9Number sold: 36 38 42 44 48 49 50 49 52Day: 10 11 12 13 14 15Number sold: 48 52 55 54 56 57a. Which method would you suggest using to predict future sales—a linear trend equation or trendadjustedexponential smoothing? Why?b. If you learn that on some days the store ran out of the specific pain reliever, would that knowledgecause you any concern? Explain.c. Assume that the data refer to demand rather than sales. Using trend-adjusted smoothing with aninitial forecast of 50 for week 8, an initial trend estimate of 2, and .3, develop forecastsfor days 9 through 16.
