QUESTION 22 Calculate the risk ratio for this study. Round to the nearest hundredth. A hypothetical study was undertaken among 600 ADHD-free children in South Carolina. The purpose of the study was to examine the effects of increased screen time during childhood on the subsequent diagnosis of ADHD by young adulthood. The children's screen time was assessed by a questionnaire, and the children were followed for 10 years. The following data were obtained from the study: Screen Time 4 or More Hours per Day Less than 4 Hours per Day Total ADHD 125 175 300 No ADHD 135 165 300 Total 260 340 600

Step 1
For the given data,
We have to calculate risk ratio.
Risk ratio :
*It is the ratio of the probability of exposed group to the group of unexposed group.
More than 4 hours per day is exposed group & (affected ADHD)
Less than 4 hours per is unexposed group & same ( affected ADHD)
Step by step
