The compressive strength of cement samples can be modeled by a normal distribution with a mean of (? + 6000) kilograms per square meter and a standard deviation of (? + 100) kilograms per square meter. Find the probability that a sample’s strength is between (? + 5800) kg/m2 and (? + 5900) kg/m2 T = 28

For quality control purposes, two same types of rain gauges that have been recently installed in the Thunder Bay region, are being inspected weekly. Based on the results of weekly inspections, each of these rain gauges is out of order 20% of the time at the end of each week. In 10% of the time, both rain gauges are out of order. Compute: (i) the probability that at least one rain gauge is out of order at the end of a week, (ii) the probability that at the end of a week both rain gauges are still working, and (iii) now denoting one rain gauge as A, another rain gauge as B, and when P(A) ≠ 0.0 and P(B) ≠ 0.0 then show that P(A/B) > P(A) and P(A∩B) > P(A) x P(B), and in your understanding in a hydrologic context, what the foregoing statements mean and/or implies?
The scores of students on a standardized test form a normal distribution with a mean of 300 and a standard deviation of 40. Using the fact that the middle 50% of the data falls within .67 standard deviations from the mean, find the lower and upper quartile scores for this test.
