Question 3 4 pts 1 Details A bag of M&M's has 2 red, 5 green, 3 blue, and 4 yellow M&M's. Suppose you randomly select two M&M's from the bag one at a time. Suppose you replace the first M&M before selecting the second one. Find each probability as a fraction in simplest form. a) the probability both M&Ms are yellow. b) the probability that the first M&M is yellow and the second M&M is red. Suppose you DO NOT replace the first M&M before selecting the second one. Find each probability as a fraction in simplest form. a) the probability both M&Ms are yellow. b) the probability that the first M&M is yellow and the second M&M is red.

For the statement below, write the claim as a mathematical statement. Use proportions to state the null and alternative hypotheses, and identify which represents the claim. According to a recent survey, 69% of college students used student loans to pay for college. Let p be the proportion of college students who used student loans to pay for college. What is the claim as a mathematical statement? A. $p < 0.69$ B. $p = 0.69$ C. $p \neq 0.69$ D. $p \leq 0.69$ E. $p \geq 0.69$ F. $p > 0.69$ Determine the null and alternative hypotheses. $H_o: p$ $0.69$ $H_a: p$ $0.69$ Identify whether the null or alternative hypotheses is the claim. Choose the correct answer below. A. The alternative hypothesis $H_a: p < 0.69$ is the claim B. The alternative hypothesis $H_a: p > 0.69$ is the claim C. The alternative hypothesis $H_a: p \neq 0.69$ is the claim. D. The null hypothesis $H_o: p \leq 0.69$ is the claim E. The null hypothesis $H_o: p = 0.69$ is the claim. F. The null hypothesis $H_o: p \geq 0.69$ is the claim

3 Selecting the best attribute at each node during decision tree learning is done by computing information gain of each attribute IG(A), and selecting the attribute with highest info. gain. Assume S is the complete sample at a certain node, Sv is the subsample having all examples with the same value for the attribute being evaluated, and H is the entropy function. Which of the following formulas correctly computes information gain? A. IG(A)= H(Sv) - ? (Sv/S) H(Sv) B. IG(A) = H(S) - ? (Sv/S) H(Sv) C. IG(A) = H(S) - ? (S/Sv) H(Sv) D. IG(A) = H(Sv) - ? (S/Sv) H(S) ? You are asked to design a two-input perceptron that implements the Boolean function ~X1 OR X2 (not X1 OR X2). Assume the independent weight is always +0.5 (assume WO=+0.5). Which of the following values for W1 and W2 are valid (effectively implement the function)? A. W1 = -0.6, W2 = 0.5 B. W1 = 0.1, W2 = -0.4 C. W1 = -0.4, W2 = -0.4 D. W1 = -0.4, W2 = 0.1
