Use the t-distribution to find a confidence interval
for a mean μ given the relevant sample results. Give the best point
estimate for μ, the margin of error, and the confidence interval.
Assume the results come from a random sample from a population that
is approximately normally distributed.
A 90% confidence interval for μ using the sample results x¯=3.5, s=0.4, and n=100
Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places.
point estimate = Enter your answer; point estimate
margin of error = Enter your answer; margin of error
The 90% confidence interval is Enter your answer; The 90%confidence interval, value 1 to Enter your answer; The 90%confidence interval, value 2 .
The point estimate is
