ANSWER:Solution 6 CRE Step 1 : Birth weight in the united states is normally distributed with a mean of 3420g and a standard deviation of 495g. We have to find the percentage of babies are born with a weight greater than 3500g Following are the steps to analyze data from Mini Tab. . Enter the dataset in stat disk graphprobability distribution. . Then choose probability view ok . Select normal distribution and compute mean and standard deviation. . Define probability value in shaded region and choose right tail x value ok From the graph we can see in the right tail region the value is 0.4358 43.58% of babies born with weight greater than 3500g.
