Q₁ A recruitment agency is trying to determine the rate at which salaries increase with age. A random sample of 51 individuals are surveyed and provide their age and salary. Say=3511.38. S-8009.11, S-7737.72. Furthermore Salary = 22.90 and Age = 39.20. For the model E(Salary) = 8 + B, Age, predict the expected salary of an individual with age 58.20 years. QA recruitment agency is trying to determine the rate at which salaries increase with age. A random sample of 50 individuals are surveyed and provide their age and salary. S-12572.39, S₂7085.18. Syy 26867.41. Furthermore Salary 87.05 and Age = 42.92. For the model E(Salary)= B + B₁Age, your estimate of Bo to three decimal places is: 03 A recruitment. t agency is trying to determine the rate at which salaries increase with age. A random sample of 59 individuals are surveyed and provide their age and salary. Szy-7730.65, Szz-6715.30, S15220.15. Furthermore Salary = 48.54 and Age = 37.98. For the model E(Salary)= Bo+ B, Age, your estimate of the standard error of B, to three decimal places is: A recruitment agency is trying to determine the rate at which salaries increase with age, and expects that a linear model: Q4 E(Salary)-Bo B₁Age is appropriate. A random sample of 47 individuals are surveyed and provide their age and salary. Sxy= 12330.60. Sxx-6645.71, Syy=27334.97. Furthermore mean Salary -73.38 and mean Age -37.06 and the standard error of 8₁-0.122. The test statistic for the test HO: B₁0 to 2 decimal places is:p
