Can you solve this one for me, and add all the calculation steps and interpretation. I also attached the related picture to this question. Thanks
5. Child care hours. The China Health and Nutrition Survey aims to examine the effects of the
health, nutrition, and family planning policies and programs implemented by national and local
governments. It, for example, collects information on number of hours Chinese parents spend taking
care of their children under age 6. The side-by-side box plots below show the distribution of this
variable by educational attainment of the parent. Also provided below is the ANOVA output for
comparing average hours across educational attainment categories.
