Consider this data as a sample of the population. (a) Calculate a point estimate of the mean oxide thickness for all wafers in the population. (Round your answer to 3 decimal places.) (b) Calculate a point estimate of the standard deviation of oxide thickness for all wafers in the population. (Round your answer to 2 decimal places.) (cl Calculate the standard error ofthe point estimate from part [a]. [Round your answer to 2 decimal places.) (d) Calculate a point estimate of the median oxide thickness for all waters in the population. [Express your answer to 1 decimal places.) (e) Calculate a point estimate of the proportion of wafers in the population that have oxide thickness greater than 430 angstrom. (Round your answer to 4 decimal places.) (a) The point estimate of the mean oxide thickness is n Angstroms. lb} The point estimate of the standard deviation of oxide thickness is n Angstroms. (C) The point estimate of the standard error of the mean is n Angstroms. (d) The point estimate of the median oxide thickness is I Angstroms. (e) The estimate of the proportion requested is
