10. Fill in the blank. In developing a 96% confidence interval estimate for some normal population mean μ, the population standard deviation σ was 10, The interval estimate was found to be 12.6 ±3.64. Had σ equaled 5, the interval estimate would be 12. Based on a sample of size n 21 drawn from a normal population, the sample mean and sample standard deviation are, respectively, 15.68 and 1.36. We use T-test to test Ho : μ 15 vs H1...

A random sample of 49 observations is used to estimate the population variance. The sample mean and sample standard deviation are calculated as 59 and 3.1, respectively. Assume that the population is normally distributed. (You may find it useful to reference the appropriate table: chi-square table or F table) a. Construct the 90% interval estimate for the population variance. (Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.) Confidence interval b. Construct the...

Fill in the blank. Hemophilia is an X-linked trait. In a population of 20,000 people in HW equilibrium, 10,000 women and 10,000 men were tested for this trait, and 15 men were found to have the disorder. The value that you calculated for the Hemophilia allele was (to 4 decimal places) _______ and there would be _______ carrier females in this population.

Explain the difference between the following: 1. A population parameter and its point estimate. 2. A population and a corresponding sample mean. 3. Explain in your own words: range, variance and standard deviation for a population.
