A researcher wishes to estimate, with 90% confidence, the population proportion of adults who think Congress is doing a good or excellent job. Her estimate must be accurate within 2% of the true proportion. No preliminary estimate is available. Find the minimum sample size needed. What is the minimum sample size needed assuming that no prior information is available? n= (Round up to the nearest whole number as needed.)

A particular part that is used as an injection device is sold in lots of 10. The producer deems a lot acceptable if no more than one defective is in the lot. A sampling plan involves random sampling and testing 3 of the parts out of 10. If none of the 3 is defective, the lot is accepted. Comment on the utility of this plan. Determine the correct parameter.

You are working on the design for a study on the proportion of adults who work remotely in the U.S. The original design sought to limit the margin of error to 0.1 and the new design seeks to limit the margin of error to 0.01. What must be the corresponding change to the minimum sample size? A. It must increase B. Nothing, because the minimum sample size doesn't depend on margin of error C. It must decrease
Another idea is to look at how a team's payroll impacts its home attendance. Higher payroll usually signals more higher-skilled players on a roster which should brings fans to the ballpark to see these players. Create 2 samples based on Team Salary and calculate average attendance, variance of attendance, and standard deviation of attendance for each sample. Sample 1 = 10 teams with the highest team salary Sample 2 = 10 teams with the lowest team salary Tip: Use Excel's sorting tool to sort the data by salary (highest to lowest), and copy the 10 highest and 10 lowest into a separate part of the spreadsheet for easier analysis. Sample 1 Sample 2 Top 10 Team Salary Bottom 10 Team Salary Sample mean attendance mil mil Sample attendance variance mil mil Sample attendance standard deviation mil mil Perform a hypothesis test to determine whether there is a difference in the mean attendance of teams between the two groups…

Company's salary is $50,000. Assume normal distribution with standard dev. being $6,000. Random sample of 30 workers, find these: Sample mean's salary is higher than $52,000. Sample mean's salary is lower than $48,000.
In a t-test of difference between means, increasing sample size will affect the:
