Suppose that Y is a normally distributed random variable. Assuming that the data is randomly sampled, use the following information to determine the sample variance. Show your work. Use three decimal places. • The sample size is 1225 • The upper limit of a 90 percent confidence interval for E [Y ] is 1.194 • The lower limit of a 90 percent confidence interval for E [Y ] is 1.006.
You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=72.1σ=72.1. You would like to be 99% confident that your estimate is within 2 of the true population mean. How large of a sample size is required?
Automobile Parts: An important manufacturing process produces cylindrical component parts for the automotive industry. It is important that the process produce parts having a mean diameter of 5.0 millimeters. The engineer involved conjectures that the population mean is 5.0 millimeters. An experiment is conducted in which 100 parts produced by the process are selected randomly and the diameter measured on each. It is known that the population standard deviation is σ = 0.1 millimeter. The experiment indicates a sample average diameter of x = 5.027 millimeters. Does this sample information appear to support or refute the engineer's conjecture?
Jimmy collected a random sample of 30 psychology majors and administered an IQ test. This group had an average IQ of M = 110. Compare this statistic to the general population, which has a mean IQ of 100 and a standard deviation of 15.   Use alpha of .05 and a two tailed test Step 1: Pick the Test: Hypotheses: Step 2: Alpha: One-tail or two-tail: Decision Rule (What is the critical value): Step 3: Calculations Step: 4 Interpretation What did you do?

A school district claims that the average salary of elementary school teachers in their district is more than the national average of $42,000. A sample of 30 elementary school teachers from that district have a mean salary $43,260. The standard deviation for the population is $5,230. At α = 0.05, test their claim that teachers in their district earn more than $42,000 per year.

Researchers conducted a study to determine whether magnets are effective in treating back pain. The results are shown in the table for the treatment (with magnets) group and the sham (or placebo) group. The results are a measure of reduction in back pain. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Treatment Sham μ μ1 μ2 n 13 13 x 0.48 0.41 s 0.76 1.42 a.
