- Is the average age of armed services personnel related to the average amount of length of service in months? The data are shown in table below. a. Draw a scatter plot. What does it show? b. Compute the value of the correlation coefficient. c. Test the significance of the correlation coefficient at a = 0.05.arrow_forwardListed below are the amounts of bills for dinner and the amounts of the tips that were left. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Use a significance level of α=0.01. If everyone were to tip with the same percentage, what should be the value of r? Bill (dollars) 31.65 53.83 87.10 103.64 60.34 109.80 Tip (dollars) 3.74 5.76 14.73 16.86 7.44 20.73 1. The linear correlation coefficient is r= 2. What are the null and alternative hypotheses? 3. The test statistic is t= 4. The P-Value is P=arrow_forwardwhat are the critical values r =?arrow_forward
- 1.Consider the accompanying data on and (%) at failure of the cheese. [Note: Theresearchers were Italian and used real mozzarella cheese, not the poor cousin widelyavailable in the United States.]a. Construct a scatter plot.b. What does the plot suggest about the nature of the relationship between the twovariables?c. Calculate coefficient of correlation between x and y. Comment on the result. 2.Scraps of iron were selected on the basis of their densities, x, and their iron contents, y,were measured. The results were as follows:x 2.8 2.9 3.0 3.1 3.2 3.2 3.2 3.3 3.4y 27 23 30 28 30 32 34 33 30(i) Plot the data(Scatter Diagram)9 | P a g e(ii) Find the regression equation of y on x by the method of least squares(iii) Comment on Goodness of fit of the fitted line(iv) Predict y for given x=3.5arrow_forwardThere is a negative correlation between the average litres of wine consumed by residents of a country and the incidence of national coronary deaths. Explain why correlation in this case does not imply causation by suggesting a third variable z that explains the correlation. Is z a common response or a confounding variable?
