57Does the hypnotism appear to be effective in reducing pain?Yes/No A study was conducted to measure the effectiveness of hypnotism in reducing pain. The measurements are centimeters on a pain scalebefore and after hypnosis. Assume that the paired sample data are simple random samples and that the differences have a distribution thatis approximately normal. Construct a 95% confidence interval for the mean of the "before-after" differences.

Big Sweets candy company is testing one of its machines in the factory to make sure it is producing more than 96% high-quality candy (Ho: P = 0.96; Ha: p > 0.96; a = 0.05). The test results in a p-value of 0.12. However, the company is unaware that it is actually producing 98% high-quality candy. What MOST likely happens as a result of the testing? O The company rejects Ho, making a Type I error. O The company fails to reject Ho, making a Type I error. O The company rejects Ho, making a Type II error. O The company fails to reject Ho, making a Type II error. O The company rejects Ho correctly.
MORE BENEFITS OF EATING ORGANIC Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data from this study. In this case, we are testing where p, and p, represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. We have n₁ = n₂ = 500. Show all remaining details in the test, using a 5 % significance level. Effect of Organic Raisins After 20 Days After 20 days, 275 of the 500 fruit flies eating organic raisins are still alive, while 170 of the 500 eating conventional raisins are still alive. ¹Proportions approximated from information given in the paper.

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.
