Suppose a population has a mean weight of u = 79.676 kg and a standard deviation of 0:22.4943. For samples of size n= 36, A sample of size n=36 is taken. Approximate the probability of observing a sample mean of less than 71.5 kg. (hint: use number 1). In calculating the z-score, round your z-score to two decimal places. Use the normal table to nd the probability and give answer to 4 decimal places. i.e. m?
