The percent iron in an ore sample was determined by two different analysts. The following data was obtained;
Analyst 1: mean iron concentration (ppm) = 11.35; standard deviation = 0.15; n = 9
Analyst 2: mean iron concentration (ppm) = 10.45; standard deviation = 0.30; n = 8
Are the population deviations are the same at the 95% confidence level?
What is the value of Student's t for this data at the 95% confidence level?
