Point estimates of the mean and standard deviation From an infinite population, you draw three samples, 49 observations each. Their means are: 921 = 4, 22 = 13, and x3 = 12 dollars. (a) Use the central limit theorem to estimate the population mean (b) Find the standard error of the mean for the three same e means. (c) Find the population standard deviation. (d) Find the probability that the mean of the next random sample will be higher than -11.42 i dollars. Draw the density graph of your answer. Page 3 of7 1038 words U)?
