To solve this problem it is necessary to develop aone sample Z-test. In R there isn’t a similar function, so we can create our function. Recalling the formula for calculating the value of z, we will write this function: $$Z=\frac{\overline{x}-\mu_0}{\frac{\sigma}{\sqrt{n}}}...
Perform the one-sample Kolmogorov-Smirnov test by usingkstest. Confirm the test decision by visually comparing the empirical cumulative distribution function (cdf) to the standard normal cdf. Load theexamgradesdata set. Create a vector containing the first column of the exam grade data. ...

Each subset of data (E.g: train and test) should be in its own directory. The path to the directory can then be given directly to either train_model() or eval_model(). Each data sample should have a text portion and an image associated with it (and a label/labels for training and...
This won't provide the benefits of FTS but it will allow searching exactly for what you need. Note that it can also be much slower, even extremely slow, depending on your query. /"- [ ]" - will return all the notes that contain unchecked checkboxes. Search filters You can also use ...

Consequently, the Mann–Whitney test was used in the data processing. The remaining data were processed in accordance with Levene's test, and it was discovered that the variance was homogenous, thus an independent sample T test was carried out. The difference was statistically significant when ...
