In cases where we do not know the sample distribution and we have sufficiently large n, then we can apply the Central Limit Theorem. That is to say, according to the CLT, x can have any distribution whatsoever, but as the sample size increases, the distribution of   will approach a normal distribution. The CLT formula is Where n is the sample size (n ≥ 30), μ is the mean of the x distribution, and σ is the standard deviation of...

1. What percent of NaCl solution (where the only solute is NaCl) would make it have a higher concentration of diffusible water as a solution with a total osmolarity of 280 mOsm/L? Please correct #2 to show a net gain of water instead of a net loss. 2. If a one-liter solution contains 280 mOsm of glucose and it also contains 280 mOsm of NaCl, then a red blood cell placed into this solution would experience a net loss of...
