Given the values n = 110, x = 0.87,
σˆn2−1 = s2 = 0.081 in a sample
(I) find a 90% confidence interval for a
population mean μ. (Round your answers to three decimal
places.)
(II) Indicate the correct interpretation of the interval
that you have constructed:
(a) 90% of all values will fall within the
interval.
(b) In repeated sampling, 90% of all intervals
constructed in this
manner will enclose the population mean;
(c) In repeated sampling, 10% of all intervals
constructed in this manner will enclose the population mean;
(d) There is a 10% chance that an individual
sample mean will fall within the interval.;
(e) There is a 90% chance that an individual
sample mean will fall within the interval.
