urable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "Wrinkle covery angle" measures how well a fabric recovers from wrinkles. Higher is better. Here are data on the inkle recovery angle (in degrees) for two types of treated fabrics: Permafresh Hylite 15 17 12 14 13 16 16 15 14 18 nanufacturer wants to know how large is the difference in mean wrinkle recovery angle. re a 98% confidence interval for the difference in mean wrinkle recovery angle: [three decimal accuracyl (three decimal accuracyl

Please examine the graph below, which is a histogram summarizing a sample of data. What can we reasonably conclude about the sample? Frequency 08 09 40 20 0 -25 -20 -15 -10 -5 Pick ONE option X 0 5 We can be certain the data in the sample are normally distributed, as the histogram shows a characteristic 'bell curve' shape. We can be certain the data in the sample are not normally distributed, as the histogram is too uneven and asymmetric. While a normal distribution is a sensible hypothesis, these data could have been generated from other distributions, or a mix of distributions. The presence of negative values means this cannot be normally distributed data. If the actual underlying data are integers, then the data could reasonably be Poisson-distributed, or from some other count process. Two or more of these statements are true.
