For each problem that requires you to use your calculator, please write the calculator command you are using in order to receive full credit. For example: normalcdf(4,5,7,1)=.02. Don't just state the value you get from your calculator. Unless otherwise stated in the problem, round answers to 4 decimal places.

D Question 4 16 pts The total energy need during pregnancy is normally distributed, with p = 2600 kcal/day and standard deviation 0' = 50 kcaI/day. A simple random sample of 36 pregnancies is taken. 1. Describe the population and sampling distribution. Be sure to include the mean, standard deviation and shape. 2. Sketch the population and sampling distributions. 3. What is the probability that one randomly selected pregnancy has a total energy need more than 75kcal/day away from the population mean? 4. What is the probability that sample mean of 36 randomly selected pregnancies have a total energy need more than 75kcal/day away from the population mean? Upload Choose a File
