Due: Tuesday at beginning lab 11/28.

SPSS:
>Compare Means

One sample T-TEST ( & Confidence Interval)
>Analyze>Compare Means>One Sample T test
(remember to enter Test Value Box with test value/population mean-0 for confidence, Mu for t-test.

*Draw a random sample with N=10 from the population of 1970 state census population in millions. I will show you how before lab starts involves a random number table (its in book).

1) A) Please create a 95% confidence interval around the sample mean (n=10) which you calculated. Please interpret your results. (by computer)

2) Test the hypothesis that your sample of ten state populations came from a population with an overall population mean of 5.0 million. Please go through the four inference procedures steps Please do calculations by hand and SPSS.
