4.3 For each of eight mice, the date of birth, date of disease, and date of death is recorded. In addition, the mice are placed into one of two groups (A or B). Given the following data, compute the time from birth to disease, the time from disease to death, and the age at death. All times can be in days. Compute the mean, standard deviation, and standard error of these three times for each of the two groups. Here are the data: RAT NO DOB DISEASE DEATH GROUP 1 23MAY1990 23JUN1990 28JUN1990 A 2 21MAY1990 27JUN1990 05JUL1990 A 3 23MAY1990 25JUN1990 01JUL1990 A 4567 27MAY1990 07JUL1990 15JUL1990 22MAY1990 29JUN1990 22JUL1990 26MAY1990 03JUL1990 03AUG1990 7 24MAY1990 01JUL1990 29JUL1990 8 29MAY1990 15JUL1990 18AUG1990 ABBBB Chapter 4 Working with Date and Longitudinal Data Arrange these data in any columns you wish.
