A civil engineering student has delivered a cylinder of concrete for the "concrete strength competition" held between universities. The strength of the student's concrete cylinder is normally dispersed with N(4X0, 9X) kN (write the last number of your student number instead of X). For example, if the last number of your student number is 4, the normal distribution will be N(440.94). The student will compete in the last place in the competition and until that point the two highest strengths in the competition are 500 kN and 350 kN.

What are the odds of the student coming second in the competition?
The student's cylinder is being tested and under a load of 450 kN the cylinder has shown no signs of breaking. What are the chances of the student winning first place?

Question 4) A civil engineering student has delivered a cylinder of concrete for the
"concrete strength competition" held between universities. The strength of the student's
concrete cylinder is normally dispersed with N(4X0, 9X) kN (write the last number of your
student number instead of X). For example, if the last number of your student number is 4,
the normal distribution will be N(440.94). The student will compete in the last place in the
competition and until that point the two highest strengths in the competition are 500 kN
and 350 kN.
a) What are the odds of the student coming second in the competition?
b) The student's cylinder is being tested and under a load of 450 kN the cylinder
has shown no signs of breaking. What are the chances of the student winning
first place?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
