This information is presented in the following table: Semester Costs (X) Sales (Y) S1 – 2020 $12,000 $40,200 S2 – 2020 $15,000 $45,000 S1 – 2021 $11,250 $38,000 S2 – 2021 $13,350 $39,500 S1 – 2022 $17,400 $46,000 S2 – 2022 $13,800 $38,000 S1 – 2023 $15,750 $44,300 S2 – 2023 $14,400 $37,800 a) Determine the equation that estimates sales for the following periods using the MCO method. Determine and interpret the coefficients and the general and individual analysis of the regression (10 points). b) Suppose that the company generates a net profit equal to 20% of sales. If information is available on inventory costs for the next 3 years, determine the net profit obtained by the company for each period (20 points). Semester Costs (X) S1 – 2024 $16,500 S2 – 2024 $17,400 S1 – 2025 $18,000 S2 – 2025 $18,750 S1 – 2026 $19,650 S2 – 2026 $20,550

1. Calcular la media de los costos y ventas (en miles de pesos):
\bar{X} = \frac{12{,}000 + 15{,}000 + 11{,}250 + 13{,}350 + 17{,}400 + 13{,}800 + 15{,}750 + 14{,}400}{8} = 14{,}368.75
\bar{Y} = \frac{40{,}200 + 45{,}000 + 38{,}000 + 39{,}500 + 46{,}000 + 38{,}000 + 44{,}300 + 37{,}800}{8} = 41{,}225

2. Calcular la pendiente (b) y la intersección (a) de la ecuación de regresión:
b = \frac{\sum (X_i - \bar{X})(Y_i - \bar{Y})}{\sum (X_i - \bar{X})^2} = 1.29375
a = \bar{Y} - b\bar{X} = 22165.02

Ecuación de regresión:
Y = 22165.02 + 1.29375X

b)
1. Para los costos futuros, se usa la ecuación de regresión para estimar las ventas:
Y_{2024_1} = 22165.02 + (1.29375 \times 16{,}500) = 39{,}397.425
Y_{2024_2} = 22165.02 + (1.29375 \times 17{,}400) = 40{,}051.2
Y_{2025_1} = 22165.02 + (1.29375 \times 18{,}000) = 40{,}462.515
Y_{2025_2} = 22165.02 + (1.29375 \times 18{,}750) = 41{,}116.825
Y_{2026_1} = 22165.02 + (1.29375 \times 19{,}650) = 41{,}565.015
Y_{2026_2} = 22165.02 + (1.29375 \times 20{,}550) = 42{,}013.2

2. Calcular la utilidad neta (20% de las ventas):
U_{2024_1} = 0.2 \times 39{,}397.425 = 7879.485
U_{2024_2} = 0.2 \times 40{,}051.2 = 8010.24
U_{2025_1} = 0.2 \times 40{,}462.515 = 8092.503
U_{2025_2} = 0.2 \times 41{,}116.825 = 8190.665
U_{2026_1} = 0.2 \times 41{,}565.015 = 8313.003
U_{2026_2} = 0.2 \times 42{,}013.2 = 8435.34

Your boss asks you to plan the sample size for a randomized, double-blind, controlled trial in the clinical development of a cure for irritable bowl disease. Current standard treatment shall be compared with a new treatment in this trial. The S3-guideline of AWM demonstrated a mean change of the summary score of the validated health related quality of life questionnaire at 8 weeks of 16 with standard deviation 23 under standard treatment. You quote the drop-out rate of 11% from literature (previous phase of clinical development). Your research yielded a clinically important effect of 4 that has been found to be the Minimal Clinically Important Difference (MCID). In order to demonstrate superiority of the new treatment over standard of care, you assume that the change in of the summary score of the validated health related quality of life questionnaire follows a normal distribution, and that the standard deviation is the same for both treatments. How many patientes would one need to recruit for the trial to demonstrate the clinically interesting difference between treatments at significance level 5% with 95% power?
