Consider the following variables. For each variable, identify its distribution as either "Exactly Normal," "Approximately Normal," or "Neither" (short for neither Exactly Normal nor Approximately Normal). of . In a certain country, retirement age is known to follow a left-skewed distribution with a mean value of 56.91 years and a standard deviation of estion 3.71 years. Suppose we take a random sample of 17 members of this country and denote the sample mean retirement age by X. The distribution of X is . Assume that the heights of sunflowers follow a Normal distribution with a mean of 238cm, and a standard deviation of 21cm. A sunflower farmer selects a random sample of 8 flowers and denotes the sample mean height by X. The distribution of X is . In a certain town, yearly wages are known to follow a left-skewed distribution with a mean of $53653.00 and a standard deviation of $1980.00. Suppose we select a random sample of 52 people and denote the sample mean yearly wage by X. The distribution of X is . In a mathematics course, it is known that 19.81% of all students fail. Suppose we select a random sample of 789 students and denote the sample proportion of fails by p. The distribution of p is . Hydrocephalus is estimated to occur in 0.082% of all people. Suppose we take a random sample of 500 people, and denote the sample proportion of members with hydrocephalus by p. The distribution of p is
