A drug company has just developed a new pill to alleviate the symptoms of allergies and colds. However, they are concerned about the variability in the amount of time until the drug becomes effective. In a sample of 10 individuals who suffer from allergies, the amount of time for the pill to take effect was recorded with a mean of 9.4 and a variance of 19.62. the lower and upper limit of a 90% confidence interval for the actual mean time until the drug becomes effective are: a. -1.98, 20.78. b. 6.86, 11.94. c. 3.19, 13.26. d. 6.83, 11.97. e. cannot be determined with the information given.
