Tindall, John E.

(PM Product Evaluation, R&D) Defense

John E. Tindall worked for Philip Morris, Inc. He prepared a supplement to a design memo detailing the statistical treatment of the data in the SEX-2 Study as written by Myron Johnson on March 3, 1969. The basic question to the SEX-2 Study was "To what extent is daily smoke intake a function of the cigarette smoke?" Mr. Tindall also provided consultative aid to Barbara Forrest in preparing the data for the treatment and supervised the computer processing. (UCSF000083-85) Mr. Tindall presented the analysis of data collected for Benson and Hedges 100's, Kent 85 and Salem 85, and according to the statistical procedures suggested by the Research Triangle Institute's proposal the shadow was used to testify hypothesis that the ratio of delivered tar to filter nicotine is a constant for each cigarette independant of the amount of tar delivered. The data for Salem, Kent, and Benson and Hedges 100's did not reject the hypothesis that the ratio of delivered tar to filtered nicotine is constant. This analysis of the Research Triangle Institute data was presented to Helmut Wakeham on August 29, 1968. (UCSF000087-95)
