Exercise 36 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 < 0.05 hence this suggests a rejection of the null hypothesis

1. The independent variable for A‚ B‚ and C is postnatal age in hours. The dependent variables for A‚ B‚ and C are systolic blood pressure‚ diastolic blood pressure‚ and mean blood pressure respectively. The relationships between these variable is direct and positive in that as the independent variable of postnatal age increases the corresponding dependent variable increases. 2. The independent and dependent variables in Figure 3 are the same as in Figure 2‚ as well as the relationship between

Provide a rationale for your answer. t = 2.03* the smallest t ratio listed in Table 2. It indicates that the cholesterol level change was statistically significant from pretest to 3 months. It is greater than the given value of p<0.05 7. Why are the larger t ratios more likely to be statistically significant? They

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
