The difference is that figure 3 displays the relationship with regard to infants with a body weight of 1001-1500 grams‚ and figure 2 deals with infants with a body weight equal to or lesser than 1000. 3. According to figure 3‚” in each instance‚ the y intercept was significantly greater (p < 0.001) than the value for

hypothesis is that the mean mobility scores for both groups are the same. As stated previously‚ since the p-value 0.005 < 0.05 this means I reject the null hypothesis. So the mean "difficulty with mobility score" for both groups must be different. 3. The researchers stated that the participants in the intervention group reported a reduction in mobility difficulty at week 12. Was this result statistically significant‚ and if so at what probability? Yes the result was statistically significant

The hardest part about this assignment is finding the center line. The center line is always X-bar-bar. (An x with two bars above it). It’s the mean of all the sample means. I’ve attached an Excel spreadsheet showing how to calculate X-bar-bar. First‚ you find the average of each sampe. There were four in this case. The average is at the bottom. Then you take those four numbers and find the average for those. I rounded up to 5.1 to make it easier to graph. So X-bar-bar = 5.1. Once you X-bar-bar
