Suppose that 21 of them were risk-averse. Formulate a one-sample hypothesis test for a proportion to test this belief. proportioH uy to ave Teir inves CIsions) is though to proportion is actualily less Determine the null hypothesis, Ho, and the alternative hypothesis, H. (Type integers or decimals. Do not round.) Compute the test statistic.

Question 2 The test statistic from a test of the following hypotheses: Ho: μ = 69 H1: μ # 69 was calculated to be z = 1.291. Calculate the associated p-value. O 1.8033 O 0.9016 O 0.1967 0.4975 O 0.7407 0.0492

Let α be any logical truth and let β be any proposition. Explain why ¬α ∨ β isequivalent to β.

can you solve the last point question 2 C please for making type I error

If we decrease the significance level (alpha) all else being equal, the power of the test will:   A. Won't change   B. Increase   C. Decrease   D. It depends – need more information

Please help step to step with Program R (CS) with explanation and final code for understanding thank you.

Qusstion is attached please need answer.

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

By using propositional variables, logical connectives, and quantifiers, determine whether the argument is valid. If it is valid, what rule of inference is being used? If it is not, what logical error occurs?
