which of the following statements most accurately represents the relationship between statistical and clinical importance? clinical importance or effect is dependent entirely upon the sample size and characteristics statistical significance does not tell us about how much of an effect was present and how important the size of the effect is in practice statistical significance is a pre-requisite for clinical importance the researcher can increase the likelihood of finding clinical importance by increasing the sample size

spectra.
Also answer the following questions about your observations: Are the lines present in the hydrogen spectrum the same lines predicted by the Bohr model the atom? Which lines, if any, are missing? Why might there be lines missing? Compare the spectral lines from your unknown substance to the other spectra you observed. Based on these comparisons, what is the identity of the unknown substance? Are there any general...
