Part (a) Suppose you make 10 measurements of the concentration and get the following values (in millions per ml of fluid), stored as R vector x: x = c(28.67, 26.89, 27.02, 29.38, 27.53, 25.65, 26.73, 27.34, 25.99, 26.24) Based on this sample, find the 95% confidence interval for the true concentration of the bacteria in millions per ml of fluid (i.e. in 106 /ml). Do not round your answer. Create R vector CI of length two, so that the first and the second entries are the lower and the upper end points of your confidence interval interval. The values should be in millions per ml ( 106 /ml). Hint: Make sure you have everything in millions per ml. Do not round your
