- In an attempt to develop a model of wine quality as judged by wine experts, data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 17 wines, a model was created using the percentages of alcohol to predict wine quality. From the results of that regression, b1=0.4386 and Sb1=0.1141. a. At the 0.05 level of significance, is there evidence of a linear relationship between the percentage of alcohol and wine quality? b. Construct a 95% confidence interval estimate of the population slope, β1. b. The 95% confidence interval is __ ≤ β1 ≤ __ (Round to three decimal places as needed.)arrow_forwardTo study how social media may influence the products consumers buy, researchers collected the opening weekend box office revenue (in millions of dollars) for 23 recent movies and the social media message rate (average number of messages referring to the movie per hour).

- The study “Evaluation of Prescribed Burning in Relation to Available Deer Browse” was undertaken at the Virginia Polytechnic Institute and State University in 1964 to determine if fire can be used as a viable management tool to increase the amount of forage available to deer during the crucial months in late winter and spring. Calcium is a required element for plants and animals. The amount taken up and stored in the plant is closely correlated to the amount present in the soil. It was hypothesized that fire may change the calcium levels present in the soil and thus affect the amount available to the deer. A large tract of land in the Fishburn Forest was selected for a prescribed burn. Soil samples were taken from 12 plots of equal area just prior to the burn on May 20, 1964, and analyzed for calcium. On July 16, 1964, postburn calcium levels were analyzed from the same plots. These values, in kilograms per plot, are presented in the following table. Do these data support the…arrow_forwardA statistics consulting center at a major university analyzed data on normal woodchucks for the university's veterinary school. The variables of interest were body weight in grams and heart weight in grams. It was desired to develop a linear regression equation in order to determine if there is a significant linear relationship between heart weight and total body weight. Use this information to answer the questions. Determine the test statistic.

A neuropsychologist is studying brainlateralization—the degree to which thecontrol of various cognitive functions islocalized more in one cerebral hemispherethan the other. This researcher is awarethat for men, being right-handed seemsto be associated with a greater degree oflateralization than does being left-handedbut that this relationship may not applyto women, who seem to be less lateralizedin general. Various tasks are used in combination to derive a lateralization scorefor each subject as shown in the followingtable.arrow_forward

To test whether CEO compensation and a company's stock performance are related, a financial analyst collected data on 12 randomly selected, publicly traded companies. For each company, the analyst looked at two variables: the percent change in stock price over the past five years (which she denoted x ) and the percent change in CEO compensation over the past five years (which she denoted y ). For these 12 companies, the least-squares regression equation relating the two variables was =y+−0.1650.046x , and the standard error of the slope of this least-squares regression line was approximately 0.028 . Using her information, test for a significant linear relationship between these two variables by doing a hypothesis test regarding the population slope β1 . (Assume that the variable y follows a normal distribution for each value of x and that the other regression assumptions are satisfied.) Use the…arrow_forward
