Q1:A certain dimension is measured on four successive items coming offa production line. This sample gives x = 2.384 and s = 0.048.a) On the basis of this sample, what is the 95% confidence interval for the population mean?b) If instead of estimating the standard deviation from a sample, we knewthe true standard deviation was 0.048, what then would be the 95%confidence interval for the population mean?

(e) Perform a two-sample (nonpooled) t-test to determine if there is a difference in the average height of men and the average height of women. Note 1: for the assumptions, there is a bit of knowledge about the variable height that will get you out of making the normal probability plots. You are welcome to state that piece of knowledge OR make the NPPs. Note 2: I highly recommend you make this faster and easier for yourself by using Data > Data Analysis > t-Test: Two-Sample Assuming Unequal Variances.(f) What clues tell you this should be a two-sample (nonpooled) t-test as opposed to paired t-test?
Consider a confidence interval, with confidence coefficient 1 - a, for the mean of a normal distribution with known variance o?, based on a random sample of n observations. How does the width of the interval change (i) as n is increased, keeping o? and a fixed; (ii) as o? is increased, keeping n and a fixed; (iii) as a is decreased, keeping n and o? fixed? The standard deviation of the lifetime of a certain type of electrical component is 144 hours. How large a sample of the components must be taken to be (a) 95%, (b) 99% confident that the error in the estimated mean lifetime of such components will not exceed (i) 15 hours, (ii) 20 hours?
