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

to figure 3‚” in each instance‚ the y intercept was significantly greater (p < 0.001) than the value for comparable lines of best fit in infants with birth weight ≤1‚000 grams.”; This is evident when comparing the y-intercepts in each graph. 4. According to the equation‚ the y-intercept is 43.2 and the slop is 0.17. “x” represents the independent variable of postnatal age in hours. 5. If the value of x is postnatal age of 30 hours‚ then the value for SBP equals 43.2 + 0.17(30) or 48

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
