An intersesting application of the normal distribution is that it can be utilized to approximate a binomial distribution. For example, lets say an unfair coin is knwon to have a probability of flipping heads 70% of the time (P=.70). If you decide to flip a coin 25 times, what is the probability that you get heads 18 or fewer times? Since a normal distibution is defined completely using the expected value and standard deviation... 1) find the expected value and standard deviation of the binomial distribution Using these values will provide us with a normal distribution that will approximate the underlying binomial distribution. Since the are under the curve represents the probability, we can find the area under of the normal distribution that directly corresponds to the probability of getting 18 or fewer heads. 2) Find the P(X<18.5). (you should convert your values before using the Z-chart) Please answer both questions, thanks

Texts: An 8 m high factory with a 10,000 m2 floor area is heated with natural gas in Edirne. For the factory, where the average indoor temperature stratification is 4°C and the air exchange coefficient is 1, make the pre-feasibility of a solar air heater using the Retscreen 4 program. Make any other assumptions necessary for the calculations and indicate these assumptions. Descriptions: 1. Determine the collector areas for three different air designs – high temperature, standard, high air volume. 2. Make a financial analysis for the three different air designs mentioned above in the Retscreen 4 program by taking the collector system cost of $100 per m2. Use up-to-date economic data for financial analysis. Assume that the system is financed with 100% equity. 3. For ±20% change in climate conditions and solar energy system performance, change the equity payback period using the Risk analysis-Sensitivity analysis page. 4. Prepare all results, including energy calculations, in the form of a report.
