The canoe team from the previous problem wishes to prove that their compressive strength of 900 psi is indeed greater than the required 860 psi. To do so, they write out a number of hypotheses:

A: Our concrete is stronger than required, μ > 860
B: Our compressive strength is great, μ = 900
C: Our concrete meets the requirement, μ = 860
D: Typical concrete is weaker than ours, μ < 900

Of these four potential hypotheses which should be the null hypothesis?

Which of the hypotheses presented in the previous problem should be the alternative hypothesis?

Let X be a random variable representing the compressive strength of concrete cubes from a particular mix. X has a normal distribution with mean and standard deviation 60.14 and 5.02 N/mm2, respectively. a. The probability that the compressive strength of a cube is between its mean value and c is 0.30. In other words P(μ £ X £ c) = 0.30, where μ is the mean value given above. What is the value of c? b. Assume that each cube...

How does the toughness of road aggregates differ from their compressive strength? Can you write a mathematical relationship, if any? A test group of the class used an old aggregate impact test machine. The weight of the hammer was about 1 kgf lower than the standard weight. Determine the percentage error in the impact value of the aggregate. Should a poor quality road aggregate give a low impact value? Justify your answer.
