Find a 90%% confidence interval for a population mean a for these values. [Round your answers to three decimal places.) (2] a = 150, * = 0.82, = 0.084 to (b) a = 80, x = 29.4, 5 - 3.44 to [c) Interpret the intervals found in part [a) and part [b). In repeated sampling, 105% of all intervals constructed in this manner will enclose the population proportion. Q There is a 90% chance that an individual sample proportion will fall within the interval. 0 90%% of all values will fall within the interval. O There is a 10% chance that an individual sample proportion will fall within the interval. In repeated sampling, 905% of all intervals constructed in this manner will enclose the population mean. You may need to use the appropriate appendi table or technology to answer this
