4. The number of inaccurate gauges in a group of four is a binomial random variable s. a) What is the sample space of x (i.e., what values can s take on)? b) If on average 1 of 4 gauges tends to fail, obtain the probabilities for having one and two inaccurate gauges, respectively. c) Obtain the probability for having two or less (p 21 inaccurate gauges. d) Graph the probability distribution of x. Is the distribution symmetrical or skewed? e) What is the average and standard deviation of x?

You are proposed to accept or reject a lottery which gives X with probability 1/3 and -1 with probability 2/3. Before accepting you receive a signal "g" (good) or "b" (bad). The signal has precision q=P(g|win)=P(b|lose)>1/2.
Unions often oppose imports from what they call low-wage countries and advocate trade barriers to protect jobs from what they often characterise as "unfair" import competition" please critically analise this statement
Have X= 1, 4, 3, 2, 5, 6, 0. and Y= 1, 3, 3, 1, 4, 7, 2. I get the least squares equation as y=15/28+23/28x. is it correct? How do I test whether the model can be used for predicting Y? How much of the variation in T is explained by variation i..
