5. The random variable X is the shear strength of a weld. It is known that X has a normal distribution with mean and variance o2. A random sample of 10 observations is taken yielding the following data (in psi): 392 376 401 367 389 362 409 415 358 375 (a) The maximum likelihood estimators for u and o2 were shown in class to be Σ1(X₁-X)² n û = X and respectively. Compute the maximum likelihood estimates of u and o² with the data given. Use the Statistics mode in your calculator. Watch the video on "Univariate Statistics with Casio Calculator" on Moodle for your calculator. = (b) Recall that Þ(z) = P(Z ≤ z) where Z N(0, 1). Express P(X ≤ 350) as a Þ(.). (a) Tao tho in find the maximum likelihood catimet. of P/X/250)
