John E. Tindall worked in Philip Morris Research & Development Product Evaluation Division.
John E. Tindall prepared a supplement to a design memo detailing the statistical treatment of the data in the SEX-2 Study as written by PM employee Myron Johnson on March 3, 1969. The basic question of 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 independent 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 of PM on August 29, 1968.(UCSF000087-95)
