Find a 90% condence interval for a population mean u for these values. (Round your answers to three decimal places.) (a) n = 150, 2 = 0.89, s2 = 0.039 to (b) n = 40, )7 = 20.3, s2 = 3.43 t0 (c) Interpret the intervals found in part (a) and part (b). Q There is a 90% chance that an individual sample proportion will fall within the interval. 0 In repeated sampling, 90% of all intervals constructed in this manner will enclose the population mean. 0 There is a 10% chance that an individual sample proportion will fall within the interval. 0 90% of all values will fall within the interval. 0 In repeated sampling, 10% of all intervals constructed in this manner will enclose the population proportion.
