In a test, there are 300 students and one-third of them bring a water bottle. Suppose that for those who bring a water bottle, the chance that each of them leaves behind his/her water bottle in the examination room after the test is 0.06.

a)Using an appropriate approximation method, find the probability that 5 or less water bottles are left behind. Carry your answers from the previous part to at least 6 decimal places in your calculation here. Give you final answer to 4 decimal places.

Suppose the total pressure in a bottle of soda water before it is opened is 40 psig (http://hypertextbook.com/facts/2000/SeemaMeraj.shtml) and that the gas mixture is 75% CO2 and 25% other gases. The temperature is 10°C. The Henry’s Law constant is 0.104x104 atm. a) If the system is in equilibrium, how much CO2 is dissolved in the soda? (For this problem,ignore reactions between the CO2 and the water.) I know the answer is about 6500 mg/L but I'm having trouble finding the...

Suppose it is desired to test the hypothesis that the mean score of students on a national examination is 500 against the alternative hypothesis that it is less than 500. A random sample of 15 students is taken from the population and produces a sample mean score of 475 and a sample standard deviation of 35. Assume the population of test scores is normally distributed. State the decision rule, the test statistic, and your decision.
