A medical researcher says that less than 83% of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 600 adults in that country, 80% think that healthy children should be required to be vaccinated. At a = 0.10, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below. (Round to two decimal places as needed. Use a comma to separate answers as needed.) Identify the rejection region(s). Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. The rejection region is O C. The rejection region is z> O D. The rejection region isz< (c) Find the standardized test statistic z. (Round to two decimal places as needed.)

Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data

Recap When Not In Use Use In Ventilated Area • Conforms To ASTM D-4236 MARKER Chisel Point 20. An example of the vertical-horizontal illusion is shown in the figure. Although the two lines are exactly the same length, the vertical line appears to be much longer. To examine the strength of this illusion, a researcher prepared an example in which both lines were exactly 10 inches long. The example was shown to individual participants who were told that the horizontal line was 10 inches long and then were asked to estimate the length of the vertical line. For a sample of n = estimate was M CS 25 participants, the average 12.2 inches with a standard deviation of s = 1.00. K. ed or nt ed te An example of the vertical- horizontal illusion a.
