Suppose the age that children learn to walk is normally distributed with mean 11 months and standard deviation 1.5 month. 7 randomly selected people were asked what age they learned to walk. Round all answers to 4 decimal places where possible. -n . What is the distribution of X? X ~ N{|:],I:]) . What is the distribution of i? 5 ~ Nl:":]l . What is the probability that one randomly selected person learned to walk when the person was between 10 and 11.5 months old? :] . For the 7 people, find the probability that the average age that they leamed to walk is between 1|) and 11.5 months old. . For part d), is the assumption that the distribution is normal necessary? 0 N00 Yes . Find the IQR for the average first time walking age for groups of 7 people.
