Teaching Assistants Stipends A random sample of stipends of teaching assistants in economics is listed. Is there sufficient evidence at the a=0.05 level to conclude that the average stipend differs from $15,000? The stipends listed (in dollars) are for the academic year. Use the P-value method. Assume the variable normally distributed. Use a TI-83 Plus/TI-84 Plus calculator. 12,283 13,185 13.419 14,356 12,000 17.604 11,981 14,000 14.000 (a) State the hypotheses and identify the claim. HP = H = S 15000 not claim 15000 claim This hypothesis test is a two-tailed ♥ test. ▼ #3
