intelligent, driven, some famous and ambitious. These are the characteristics of individuals that are perceived as being the highly successful members of our society. Successful individuals are termed as “outliers”, people who fall outside the normal acumen of human experience. Gladwell (2008) maintains that the way in which success is measured is wrong. Further, he argues that people are more a product of their environment, culture, life experiences and even when a person was born. Andrew

Review 5. State the main points of the Central Limit Theorem for a mean. The most important result from sample mean is the Central Limit Theorem. The Central Limit Theorem states that a large sample size n, the sampling distribution of the mean approaches a normal distribution. 6. Why is population shape of concern when estimating a mean? What does sample size have to do with it? Population shape is in concern when estimating a mean because if the shape relates to the frequency of values that

allows us to approximate the shape of the sampling distribution of X even when we don’t know the shape of the population distribution” (Doane & Seward, 2007, p. 299). 6. Why is population shape of concern when estimating a mean ? What does sample size have to do with it? The shape of a population is of concern when estimating a mean because the shape can determine if a population is normal thus providing the normality of the distribution of the sample mean. According to Applied Statistics

A). B). Having a population mean of 39.85 and a population standard deviation of 2.07; the normal curve that should be used for chest circumferences is N=39.85, 207 C). Use the table on page 254 to find the percentage of militiamen in the survey with chest circumferences between 36 and 41 inches, inclusive. Note: As the circumferences were rounded to the nearest inch, you are actually finding the percentage of militiamen in the survey with chest circumference between 35.5 and 41.5 inches.
