Sales delay is the elapsed time between the manufacture of a product and its sale. according an article it is quite common for investigators to model sales delay using a lognormal distribution. for a particular product, the cited article proposes this distribution with parameter valuesμ = 2.07 and σ2 = 0.06 (here the unit for delay is )what are the variance and standard deviation of delay time? (round your answers to two decimal places.) variance months2 standard deviation months(b)what is the probability that delay time exceeds 12 months? (round your answer to four decimal )what is the probability that delay time is within one standard deviation of its mean value? (round your answer to four decimal )what is the median of the delay time distribution? (round your answer to two decimal places.)months(e)what is the 99th percentile of the delay time distribution? (round your answer to two decimal places.)months(f)among 10 randomly selected such items, how many would you expect to have a delay time exceeding 8 months? (round your answer to three decimal places.)items

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
