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 48.3. 6. If the value of x is postnatal age is 30 hours‚ then SBP = 50.3 + 0.12(30) or 53.9. 7. The SBP reading for question 6 is higher than that of question 5. This is mostly due to the significant difference in y-intercepts. 8. If the value of x is postnatal age is

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
