. Suppose that 36 items from a production line are measured. You don’t know the actual shape of the population distribution, but you know that the population mean and standard deviation of the measurements are 50mm and 4mm, respectively. Find the probability that the sample mean of the 36 items will lie between 49 and 51mm.

    3.) today you took 16 randomly sampled widgets from your new production line (which makes thousands per day) and measured dimension x. You obtained a sample mean of 17.63 mm. You know from how long experience with your production process that the population standard deviation of x is 0.25 mm and the distribution of x is very close to norma. What is the 95% confidence interval for the population mean of x? You may either give a low & high...
