Question
THE NEXT THREE QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION: A 90% confidence interval about a population proportion is computed via a random sample size n. The interval is written as 0.45 < p < 0.59. 4) The point estimate for this interval is: A) 0.59 B) 0.45 C) 0.52 D) 0.50 5) The error bound for this interval is: A) 0.07 B) 0.04 C) 0.01 D) 0.05 6) The sample size (n) for this interval is: A) 200 B) 275 C) 139 D) 315 7) Data collected by child development scientists produced the following 90% confidence interval for the average age (in months) at which children say their first word: 10.1 < µ(age) < 13.4. A) Based on this sample, we can say, with 90% confidence, that the mean age at which children say their first word is between 10.1 and 13.4 months. B) We are 90% sure that a child will say his first word when he is between 10.1 and 13.4 months old. C) We are 90% sure that the average age at which children in this sample said their first word was between 10.1 and 13.4 months. D) 90% of the children in this sample said their first word when they were between 10.1 and 13.4 months old. 8) The difference between the sample mean and the population mean is called: A) sampling error. B) mean variance. C) population variance. D) sample variance. 9) The shape of the uniform probability distribution is: A) rectangular. B) positively skewed. C) negatively skewed. D) bell-shaped.
