5. The best way to indicate the relative position of a score in a sample is to find the mean b. standard deviation C. percentile d. correlation coefficient e. variance 6. A large study was recently undertaken to determine who is and who is not covered by health insurance in the United States. From this study, the following table was produced. Age Category Has Health Insurance Has No Insurance Under 30 183 130 30 to 50 336 127 Over 50 193 31 If one person is selected at random, the probability he/she is under 30 or has insurance is equal a. 0.193 b. 0.130 C. 0.288 d. 0.224 e. 0.842 f. 0.481 7. The Central Limit Theorem is one of the most important and useful concepts of statistics. It forms a foundation for estimating population parameters and hypothesis testing and states that a. as the sample size increases, the sampling distribution of sample means approaches an F distribution, regardless of the distribution of the original population. b. as the sample size increases, the sampling distribution of sample means approaches a Student (t) distribution, regardless of the distribution of the original population. C. as the sample size increases, the sampling distribution of sample means approaches a normal (z) distribution, regardless of the distribution of the original population. d. as the sample size increases, the sampling distribution of sample means approaches a chi-square(x )distribution, regardless of the distribution of the original population e. as the sample size increases, the sampling distribution of sample means approaches a binomial distribution, regardless of the distribution of the original population
