    mean = mean(alctry)                                           t = 1.1e+05

Ho: mean = 292.0672                              degrees of freedom =    16148

Ha: mean < 292.0672         Ha: mean != 292.0672          Ha: mean > 292.0672

Pr(T < t) = 1.0000         Pr(|T| > |t|) = 0.0000          Pr(T > t) = 0.0000

t-Test for One Sample Mean 1. Let’s assume that lab rates require an average of 32 trials in a complex water maze before reaching a criterion of three consecutive error-less trials. To determine whether a mildly adverse stimulus has any effect on performance, a sample of 7 lab rats were given a mild electric shock just before each trial. Given research results that show a sample mean of 34.89 and a sample standard deviation of 3.02, test the null hypothesis...

The California Standardized Testing and Reporting (STAR) dataset contains data on test performance, school characteristics and student demographic backgrounds. The data used here are from all 420 K-6 and K-8 districts in California with data available for 1998 and 1999. Test scores are the average of the reading and math scores on the Stanford 9 standardized test administered to 5th grade students. TESTSCR: AVG TEST SCORE (= (READ_SCR+MATH_SCR)/2 ); STR: STUDENT TEACHER RATIO (ENRL_TOT/TEACHERS); Using the provided table, write down...
