Constructing and Interpreting Confidence Intervals

Collect 50 or more quantitative data items. Use the same method of collecting 50 or more data items that you used in the Module 1 discussion. Then, construct a 90% confidence interval for the population mean, p.
View an example on how to use StatCrunch (with data) to compute confidence intervals for the population mean.
Briefly describe your data set *Include your Statcrunch report, either as an attachment or (even better) paste is into your discussion post Write down your sample size From your data, what is the point estimate, g, of the population mean? What is the sample standard deviation? *Write down the confidence interval that you obtained. Interpret the result. What is the margin of error?
