Answer and explain the reason with showing work

15. The t-statistic associated with the null hypothesis that the slope coefficient is equal to 1 (Ho: B2 = 1) is: A. 1.732 B. -1.732 C. 1.567 D -1.567 16 The F-statistic associated with the null hypothesis that the true coefficient of determination is zero (Ho: IR2 = 0) is: The residual associated with the second observation in the simple regression above is: 0 -0.5 0.5 A random sample of 36 world-ranked chess players provides the following sample statistics, where the bar over the variable represents the sample means and where's denotes the sample standard deviations: Number of hours of study per day: X : 6.2, sx - 1.3 Yearly winnings: Y = $208,000, sy - $42,000 Correlation: rxy = 0.15 Based on this data, the resulting ordinary least squares regression equation is approximately equal to: A. Y = 178,000 + 4,850X, B. Y = 169,000 + 6,300X, Y, = 14,550 + 31,200X, D. Y, - -52,000 + 42,000X
