Question: Physical Sciences Carlinville, Illinois, has just started an ambitious recycling program. Special trucks collect recyclable products once a week, sorted into barrels of paper, glass, and plastic. The amount of glass recycled per week by a single household is normally distributed with mean μ = 27 pounds and standard deviation s 5 7 pounds. Suppose 12 households are randomly selected.
a. What is the probability that the total glass collected for the 12 homes, T, will be less than 350 pounds?
b. Find a value g such that P(T ≥ g) 5 0.05.
c. If the total glass collected for the 12 homes is more than 400 pounds, the recycling plant will make a profit. Find a value of m such that the probability of making a profit is 0.10.

In 36 randomly selected seawater samples, the mean sodium chloride concentration was 23 cubic centimeters per cubic meter and the standard deviation was 6.7 cubic centimeters per cubic meter (cc/cm).
1) We test the null hypothesis H0: μ = 10 and the alternative Ha: μ ≠ 10 for a normal population with σ = 4. A random sample of 16 observations is drawn from the population and we find the sample mean of these observations is x = 12. The P-value is c..
