Using the information below calculate the predicted value for Y for the given value of X. Y (Dependent Variable) = Cost of a house in thousands of dollars (i.e. Y = 1 means one-thousand dollars) X (Independent Variable) = size of the house in hundreds of square feet (i.e. X = 1 means one-hundred square feet) yhat = 10 + 12.3*X On average how many thousands of dollars will a house cost if it is 15 hundred square feet (round your answer to 4 decimal places)?

3 students аpply tо а PhD prоgrаm. The prоgram rejects 25% of all applicants. Students are accepted and rejected independently of each other. Let the random variable X represent the number of the 3 students who get rejected into the PhD Program. What is the probability that 1 student is rejected to the program if it is known that at fewer than 2 students will be rejected? (round your answer to 4 decimal places) (Hint: Binomial distribution with P=25% and n=3, and conditional probability)
4 students аpply tо а PhD prоgrаm. The prоgram accepts 70% of all applicants. Students are accepted and rejected independently of each other. Let the random variable X represent the number of the 4 students who get accepted into the PhD Program. (Hint: Binomial distribution with n=4, P=70%) What is the probability that more than 2 students are accepted to the program? (round your answer to 4 decimal places)
