Which statements are true about LASSO linear regression?   Group of answer choices has embedded variable selection by shrinking the coefficient of some variables to exactly zero. has one hyper-parameter lambda (The regularization coefficient) which needs to be tuned if there are multiple correlated predictors lasso will select all of them adds the L2 norm of the coefficients as penalty to the loss function to penalize larger coefficients

2. An airline wants to evaluate the depth perception of its pilots over the age of fifty. A random sample of n = 14 airline pilots over the age of fifty are asked to judge the distance between two markers placed 20 feet apart at the opposite end of the laboratory. Assume we don't know the population standard deviation. The sample data listed here are the pilots' error (recorded in feet) in judging the distance. 2.9 2.6 2.9 2.6 2.4 2.0 2.3 2.2 2.5 2.3 2.8 2.5 2.7 2.6 Show a histogram of the data.
