Based on the five trials, the group determines that the average concentration of the standard is 80.5 ppm with a standard deviation of 0.5 ppm. Using the equation for the Student's t confidence interval found in Appendix 1 of your lab manual and the t-value for a 95% confidence interval, calculate the confidence interval for which there is a 95% chance of finding the "true value" of the standard solution's concentration based on the data. Put your answer in the format # lower limit < "true value" < # upper limit. (Appendix 2 has an example that may be helpful.)
