An article in Cancer Research "Analyses of littermatched time-to-response data, with modifications for recovery of interlitter information," (1977, Vol. 37, pp. 3863-3868) tested the tumorigenesis of a drug. A total of 41 rats were randomly selected from litters and given the drug. The times of tumor appearance were recorded as follows: 101, 104. 104. 77. 89. 88, 104, 96. 82, 70. 89. 91, 39. 103, 93, 85. 104, 104. 81, 67. 104, 104, 104. 87, 104, 89, 78, 104, 86. 76, 103. 102, 80, 45, 94, 104, 104. 76. 80. 72.73 Calculate a 99% confidence interval on the standard deviation of time until a tumor appearance. Assume population is approximately normally distributed. Round your answers to 2 decimal places. i 13.5458 SOS i 19.6454 Statistical Tables and Charts
