Fix the roads! - The Township Board of Meridian Township wants to know how much public support there is for raising property taxes to fix and maintain the roads in the township. They randomly surveyed Township residents and calculated a 99% confidence interval for the actual proportion of Meridian Township residents who are in favor of the tax increase to be (0.59, 0.61). 1. What is the sample proportion? Give the exact answer as a decimal. 2. Which of the following statements must be true? OA. A 95% confidence interval calculated using the same survey data will include fewer plausible values for the population proportion. OB. If a different sample of 470 residents were to be selected, then there is a 99% chance that the new sample proportion will be between 0.59 and 0.61 OC. If the sample size had instead been 940 residents, then the 99% confidence interval would be half as wide as the one stated above. 3. What is the margin of error for this confidence interval? Give the exact answer as a decimal. ME = 4. What is the standard error for this confidence interval? Round your answer to 4 decimal places. SE, = 5. What is the 90% confidence interval using the same survey data? )

Arrange these steps in the correct order to prove that if you have an 8-gallon jug of water and two empty jugs with capacities of 5 gallons and 3 gallons, respectively, then you can measure 4 gallons by successively pouring some of or all of the water in a jug into another jug in the correct order. Rank the options below. Fill the 3-gallon jug from the 5-gallon jug, leaving (3, 2, 3). Empty the 5-gallon jug's contents into the 3-gallon jug, leaving (6, 0, 2), and then fill the 5-gallon jug from the 8-gallon jug, producing (1, 5, 2). Fill the 5-gallon jug from the 8-gallon jug, leaving the contents (3, 5, 0), where the ordered triple is used to record the amount of water in the 8-gallon jug, the 5-gallon jug, and the 3-gallon jug, respectively. Top off the 3-gallon jug from the 5-gallon jug, and there will be (1, 4, 3), with four gallons in the 5-gallon jug. Pour the contents of the 3-gallon jug back into the 8-gallon jug, leaving (6, 2, 0). ❤ ← ←
