MetaSuppose that a researcher, using data on class size (CS) and average test scores from third-grade classes, estimates the OLS regression Y = β0 + β1CS, SER = σ^2 () () Construct a 95% confidence interval for β1, the regression slope coefficient. The 95% confidence interval for β1, the regression slope coefficient, is (    negative 9.89,    negative 1.40). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis : β1 = 0 is    enter your response here. (Round your response to four decimal places.) Without doing any additional calculations, determine whether β1 is contained in the 95% confidence interval for β1.

ACC 323 Ch 20: Change in Depreciation Estimates Fun Company purchased equipment on 1/1/Y1 for $20,000. At that time, management estimated the equipment would be useful for 10 years and have a residual value of $2,000. Fun Company uses straight line to depreciate all of their PP&E. On 6/15/Y6 management changed the estimated total useful life of this asset to 7 years and changed the estimated residual value to $1,000. Fun records depreciation at the end of each month. Calculate depreciation expense for this asset for Year 1. Dep. Exp. ($20,000 - $2,000) / 10 years $1,800 Prepare the regular year 1 end-of-month SL depreciation JE for this asset. $1,800/12 months $150/month DR Depreciation Expense 150 CR Accumulated Depreciation 150 Calculate the book value of this asset at the point in time the change in estimates took effect. 11,000 Calculate depreciation expense for this asset for Year 6. 5,000 Prepare the AJE needed on 6/30/Y6 for this asset.

Q3: (5 pts): Because of a dust storm, certain type of insects were dispersed. It was recorded that the area of spreading does not exceed 2 km in just 12 min no more recording was taken after 15 min. the concentration profile is given as \begin{equation*} c_i = \frac{2M}{(4\pi Et)^{3/2}}e^{-r^2/4Et} \end{equation*} Develop an equation for finding the dispersion coefficient assuming that the radius of dispersion is related to time as R = 3D*(t/t<sub>end</sub>).
