Errors assigned to random variables should not be specified to more than 2 significant figures.
Hello, I need help solving the following question.
The famous iris dataset (the first sheet of the spreadsheet linked above) was first published in 1936 by Ronald Fisher. The dataset contains 50 samples from 3 iris species: setosa, virginia, and versicolor. Four features are measured, all in cm: sepal length, sepal width, petal length, and petal width.
What is the equation for the least square regression line where the independent or predictor variable is sepal length and the dependent or response variable is sepal width for iris setosa?
cm
Round to three decimal places.
Round to three decimal places.
From time to time we check our time, do you encounter random or systematic errors?How to minimize the rondom or systematic error?
