Chapter 11 – Question 24 (p. 351): At the .05 significance level‚ is the number of units produced on the night shift larger? H0: µ1 ≤ µ2 H1: µ1 > µ2 Z critical value: 1.645 x̄d (µ1): 351 x̄n (µ2): 345 σ^2d: 21 σ^2n: 28 Nd: 54 Nn: 60 Z=(351-345)/SQRT((28^2/60)+(21^2/54))=1.302 Fail to reject the null. Z is less than the critical value; therefore‚ the number of units produced on the night shift is less than the number of units produced on the day shift. Chapter 11 – Question

Laura Cortez Science Per. D 11/28/12 Soccer Ball Lab I. INTRODUCTION Speed‚ distance‚ time‚ and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed‚ distance‚ time‚ and acceleration. Distance and time are two formulas that are used to determine speed and time. For example‚ distance equals speed multiplied with time given‚ time equals distance divided by speed‚ and speed is

THE EFFECTS OF CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis
