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 a new standardized test is given to 100 randomly
selected third-grade students in Connecticut. The sample average
score x¯ on the test is 58 points, and the sample standard
deviation, sx, is 8 points.
2.1 The authors pan to administer the test to all third-grade
students in Connecticut. Construct 95% confidence interval for the
mean score on all Connecticut third graders. (5 points)

Suppose a new standardized test is given to 97 randomly
selected third-grade students in New Jersey. The sample average
score Upper Y overbarY
on the test is 56 points and the sample standard deviation, s
Subscript Upper YsY, is 10 points. The authors plan to
administer the test to all third-grade students in New Jersey.
1. The 95% confidence interval for the mean score of all New
Jersey third graders is (round to two decimal places).
2. Suppose the same...

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

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.
