Data management systems are fast becoming required components in many biology laboratories as the role of Abstract computer-based information grows. Although the need for data management systems is on the rise, their inherent complexities can deter the full and routine use of their computational capabilities. The significant undertaking to implement a capable production system can be reduced in...

O-Phenyl (tert-butyl­amido)(p-tolyl­amido)­phosphinate

In the title mol-ecule, C(17)H(23)N(2)O(2)P, the P atom has a distorted tetra-hedral environment. The P-N bond to the tolyl-amido fragment is 1.642 (4) Å while that to the butyl-amido fragment is 1.629 (3) Å. The dihedral angle between the two benzene rings is 82.3 (2)°. In the crystal, adjacent mol-ecules are linked via weak N-H⋯(O)P and N-H⋯N hydrogen-bonding inter-actions into an extended ch...

April 13 - 24 Instructor : Brian Powers 19 . 1 Statistical Hypotheses

We never know with certainty the validity of a hypothesis unless we examine the entire population. What we can say is the probability of observing our sample data if the hypothesis was correct. If this probability is extremely small we would argue that it is unlikely that the hypothesis is valid. We then “reject the hypothesis.” The null hypothesis (denoted H0) is the hypothesis we test, the re...
