Each of the digits in a raffle is thought to have the same chance of occurrence. The table shows the frequency of each digit for consecutive drawings in a California lottery. Perform the chi-square test to see if you reject the hypothesis at the 0.02 significance level that the digits are from a uniform population. Digit Frequency Digit Frequency 0 34 5 32 1 34 6 33 2 59 7 36 3 31 8 20 4 26 9 45 picture Click here for the Excel Data File a. State the decision rule. Use 0.02 significance level. (Round your answer to 3 decimal places.) $H_0$: The digits are uniformly distributed. $H_1$: The digits are not uniformly distributed. Reject $H_0$ if chi-square > b. Compute the value of chi-square. (Round your answer to 3 decimal places.) Chi-square c. What is your decision regarding $H_0$? $H_0$: The digits evenly distributed.

The purchased equipment cost, PEC (or delivered equipment cost, E) for a plant which produces 70000 ton aniline per year is estimated to be 110 x 106 TL. All other costs are close to the average values found for typical chemical plants. The cost data: Raw Material and catalyst cost, CRM= 15 x 106 TL/year Operating Labor Cost, COL= 5 x 106 TL/year Utility Cost (Electricity, water, etc.), CUT= 6 x 106 TL/year Waste Treatment Cost, CWT= 4 x 106 TL/year Selling Price of Aniline: 3.5 TL/kg a. Estimate Fixed Capital Investment (FCI) and Total Capital Investment b. Estimate manufacturing cost in TL/year and TL/kg of aniline c. Estimate Annual Net Profit (Tax rate=0.25 x Income) d.

25. Prove that if n and k are integers with 1 ? k ? n, then \\ $k \binom{n}{k} = n \binom{n-1}{k-1}$, \\ a) using a combinatorial proof. [Hint: Show that the two \\ sides of the identity count the number of ways to se- \\ lect a subset with k elements from a set with n ele- \\ ments and then an element of this subset.] \\ b) using an algebraic proof based on the formula for $\binom{n}{r}$ \\ given in Theorem 2 in Section 6.3.
