- According to the picture attached of the resdiual plot, pelase select the statement that is true. All the assumptions are met. There is problem of heteroscedasticity. There is problem of collinearity. We should include higher order terms.An aircraft company wanted to predict the number of worker-hours necessary to finish the design of a new plane. Relevant explanatory variables were thought to be the plane’s top speed, its weight, and the number of parts it had in common with other models built by the company. A sample of 27 of the company’s planes was taken, and the following model was estimated:y = β0 + β1x1 + β2x2 + β3x3 + εwherey = design effort, in millions of worker-hoursx1 = plane’s top speed, in miles per hourx2 = plane’s weight, in tonsx3 = percentage number of parts in common with other modelsThe estimated regression coefficients were as follows:b1 = 0.661 b2 = 0.065 b3 = -0.018and the estimated intercept was 2.0.Predict design effort for a plane with a top speed of Mach 1.0, weighing 7 tons, and having 50% of itsparts in common with other models.Can we use a parametric test or non-parametric test if we wanted to analyze two data sets with the first data set (old) being normally distributed while the second data set (young) is not normally distributed?
- We don't want to impose a strict set of rules concerning "how"to draw a histogram for fear that we might miss the main point of drawing a histogram. a. To label the axes properly so as to use a good "marketing" approach to the graphical display b. To draw the histogram neatly, as close to a computer rendering as possible c. To use helpful values or in point so that the histogram spins are easy to understand d. To describe the shape of the data and summarize the main features observed in the data setConstruct a well labeled box plotGaydar Exercise 10 in Chapter 1 describes a study thatshowed that heterosexual women, during ovulation, weresignificantly better at correctly identifying the sexualorientation of a man from a photograph of his face than women who were not ovulating. In other words, ovula-tion improves a woman’s “gaydar.” Near ovulation, on average women correctly identified the orientation ofabout 65% of the 100 men shown to them. If this is theprobability of correctly identifying the orientation of aman in any given photograph, what is the probability awoman would correctly classify 80 or more of the men(as two women in the study did)?
- Dr. Phil wanted to know if mothers give more hugs to their children than fathers do. He used 8 married couples so that each mother and father would be matched on the number of children for his sample. Dr. Phil then asked each parent to report the number of hugs that they gave their children over the course of 2 weeks. Assume the parametric assumptions were NOT violated. Conduct an appropriate statistical test for him using alpha .05 and the eight steps of hypothesis testing. Note: more information given in table than is neededThe shape of the mean-variance frontier that results from the combination of a riskless and arisky asset is…..:a. Is U-shaped, tilted 90 degrees clockwise.b. Is a straight line passing from the mean-variance points of the two assets.c. Is a hyperbola.d. Consists of two straight lines, each connecting one of the two assets to a risk-freeportfolioPhil wanted to know if mothers give more hugs to their children than fathers do.

Mesokurtic Platykurtic GaussianA stemplot of a set of data is roughly symmetric, but a quantile plot does not show a straight line. What conclusion can we draw?Pigmented makeup products like mascara and eye shadow may contain metal (e.g., nickel) allergens. Is a nickel allergy more likely to occur in women who report cosmetic dermatitis from using eye shadow or mascara? In a sample of 126 women with cosmetic dermatitis from using eye shadow, 11 were diagnosed with a nickel allergy. In a sample of 266 women with cosmetic dermatitis from using mascara, 26 were diagnosed with a nickel allergy. Use this information to complete parts a through c below.
