Question Help Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than CorTelation coeff. rl0 973725 weight? If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of a= 0.05. Correlation Results Critical r: +0.268085 P-value (two tailed): 0.000 Determine the null and alternative hypotheses. Ho P H1 P (Type integers or decimals. Do not round.) Identify the correlation coefficient, r. (Round to three decimal places as needed.) Identify the critical value(s). (Round to three decimal places as needed.) O A. There are two critical values at r= ± B. There is one critical value at r=

variance in hypothesis testing which is tricky to understand. Explain what this is in common terminology, without using statistical terms and jargon. What is it and why is it important?

Included in results from car crash tests are loads​ (pounds) on the left femur and right​ femur, and those values are shown in the table below. What characteristic of the data suggests that the appropriate method of analysis is​ two-way analysis of​ variance? That​ is, what is​ "two-way" about the data entered in the​ table?     A. The load values are categorized using two different factors of femur​ (left or​ right) and size of car​ (small, midsize, or​ large).   B. The data is measured in​ pounds, part of the imperial​ system, which is inherently​ two-way.   C. There are two possiblities for the​…

Part D and E

What does a correlation coefficient do?   Question  options: a It simplifies a complex pattern involving many scores into one easily interpreted statistic. b It allows us to draw conclusions about whether one variable causes another variable. c It summarizes the X scores and the Y scores separately. d It creates a correlational design, rather than an experimental design.
