The accompanying data on flexural strength (MPa) for concrete beams of a certain type was introduced in Example 1.2.

a. Calculate a point estimate of the mean value of strength for the conceptual population of all beams manufactured in this fashion, and state which estimator you used.
b. Calculate a point estimate of the strength value that separates the weakest 50% of all such beams from the strongest 50%, and state which estimator you used.
c. Calculate and interpret a point estimate of the population standard deviation s. Which estimator did you use?
d. Calculate a point estimate of the proportion of all such beams whose flexural strength exceeds 10 MPa.
e. Calculate a point estimate of the population coefficient of variation sym, and state which estimator you used.
