A twо-tаil prоpоrtion test uses α = 0.01. Which criticаl vаlues are correct?
The Utаh Divisiоn оf Nаturаl Resоurces is studying the black bear population in Utah. They tracked, tranquilized and collected data on 12 black bears, as shown in the table below. In order to make further data collection easier, they want to create a formula for estimating a bear's weight based on just its Length and Sex (females are coded 1 and males 2), because they have found a way to take those measurements from a distance, without having to tranquilize the bear. In order to do that, they need you to analyze the data and answer the following questions.What is the correlation between Sex and Weight? [corsw] (round to 2 decimals)What is the correlation betwen Length and Weight? [corlw] (round to 2 decimals)What is the correlation betwen Chest and Weight? [corcw] (round to 2 decimals)How much of the variation in a bear's weight is explained by a regression model that uses Length and Sex to estimate Weight? [mr2] (round to 2 decimals)At what level is the regression statistically significant (i.e.,Sig.F)? [sig] (round to 2 decimals)What is the coefficient of Sex in the regression equation? [ms] (round to 2 decimals)What is the coefficient of Length in the regression equation? [mt] (round to 2 decimals)What is the intercept in the regression equation? [int] (round to 2 decimals)If a male bear is observed, with a length of 66, what is its estimated weight, based on the regression model? [estw] (round to nearest whole number - no decimals)How much will the regression model typically be off (std error) in predicting the weight of a bear?
