A manufacturer claims that the tensile strength of a certain composite (in MPa) has the lognormal distribution with µ = 4, and σ^2 = 0.16. Let X be the strength of a randomly sampled specimen of this composite. Find the 60th percentile of the tensile strength (use the number that is closest in the table).

The tensile strength X of paper, in pounds per square inch, has p=30 and 0=3 random sample ot size n=100 is taken from the distribution of tensile strengths. Compute the probability that the sample mean is greater than 293 pounds per square inch

The breaking strength X of a certain rivet used in a machine engine has a mean 6000 psi and standard deviation 400 psi. A random sample of 64 rivets is taken. Consider the distribution of X, the sample mean breaking strength. What is the probability that the sample mean falls between 5850 psi and 6150 psi? What sample n would be necessary in order to have P(5940 < X < 6060) = 0.90?
Q1 (a) A researcher studied the tensile yield strength of steel. She performed tests on 20 steel samples and obtained a mean (X̄) of 305 MPa with a standard deviation (s) of 16 MPa. Based on her research she claimed that the tensile yield strength of steel generally exceeds 300 MPa. (i) Construct a 95% confidence interval for the population mean assuming that the population is normally distributed. (ii) Validate the researcher's claim that the tensile yield strength of steel generally exceeds 300 MPa.
