Grade & Sec A. Complete the following statements by writing the correct word or words and formulas. 1. The Lof an interval estimate of a parameter is the probability that the interval estimate contains parameter, and it describes what percentage of intervals from many different samples contains the unknown population parameter 2.The confidence level has its corresponding These coefficients are used to find the margin of error. is a range of values that is used to estimate a parameter. This estimate may or may not contain the true parameter value. 3. The Lower limit is obtained by using coefficient whích is called 3. The the formula while the Upper limit is obtained by using the formula Martina reads that the average age of graduate students is 33 years old. She wanted to estimate the mean age of the graduate students at her university, so she took a random sample of 30 graduate students. She found that their mean age was X-31.8 at a 95 % confidence level with 1.54 margin of error, Questions: 1. What is the lower limit? 2. What is the upper limit? 3. What is the confidence interval? 4. Based on the interval you get, is it plausible that the mean age of all graduate students at her university is also 33 years?
