The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. Use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to AC voltage. The values of the parametiers depend on the voltage and temperature; suppose 20 and 220. a) wprobby and is an meet250 Less man 250 more than 2007 (under and to the Pos than 250 7628 more than 300 what is the probability that a specimen's fetime is between 100 and 2501 (Round your answer to four decimal places) (c) Whatvalue (in br) in such that exactly Sole of all specimens have lifetimes exceeding that value?

Suppose that a scientist takes experimental data on the radius of a propellant grain Y as a function of powder temperature x₁, extrusion rate X₂, and die temperature x3. The accompanying data set is available below. Complete parts (a) and (b) below. Click here to view the coded data. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. (a) A case can be made for eliminating x₁, powder temperature, from the model since the P-value based on the F-test is 0.3488 while P-values for X₂ and x3 are near zero. Reduce the model by eliminating x₁, thereby producing a full and a restricted (or reduced) model, and compare them on the basis of R² adj The full model is ŷ = 127.50 + (1.25) x₁ + (18.25) x₂ + (26.25¹) x3. (Round to two decimal places as needed.) The restricted model is ŷ= 127.50 + (18.25¹) x₂ + (26.25) X3. (Round to two decimal places as needed.) For the full model, R² = 0.991,…
