... Repeated holdout method, 1 Holdout estimate can be made more reliable by repeating the process with different subsamples In each iteration, a certain proportion is randomly selected for training (possibly with stratification) The error rates on the different iterations are averaged to yield a ...

P-value = 0; reject Ho since p-value < ; The data strongly supports the claim that the salinity level is higher in the winter. 7. one sample t-interval ; conditions: Random seedlings given; Independence is reasonable since one seedling’s height doesn’t affect another’s height. large enough sample s ...
