Question
Since the course satisfies requirements for actuarial credentials, academic integrity standards will be enforced strictly 1. A research team conducted a pilot study of whether a traiming program improved the productivity of a firm's workers. They took a random sample of n = 3 workers and measured their productivity I before and after the training program. The average productivity increase was y, 566 units, and the sample variance of the productivity increase was 16.7 (the divisor in the variance was n-1). Test the null hypothesis that E(Y) 0against the alternative that E(Y)0. Use levels of significance 0.10.0.05. and 0.01. This problem is worth 40 points
