It is known that a certain measurement is normally distributed with mean 1.50 cms and standard deviation 0.2 cm. -Find the measurement above which lies the biggest 4.01% of all components. Gauges are used to reject all components where a certain dimension is not within the specification 1.5 + k. -Determine the value of k such that the specifications cover 95% of the measurements. -Using the normal distribution, what is the approximate probability that at least 25 of 1000 of these components have dimensions of more than 1.856
