- An urban comminity would like to show that the incidence of breast cancer is higher in their area than in a nearby rural area. If it is found that 20 out of 200 adult women in the urban comminity have breast cancer and 20 of 300 adult women in the rural community have breast cancer, can we conclude at the 0.025 level of 1 significance that breast cancer is more prevalent in the urban comminity?In a sample of 137 leopards selected randomly from one preserve, it is found that 7 of them have respiratory problems.

- During the second semester of SY 2019 – 2020, students in Mathematics in the Modern World were asked to rate their extent of preparation and level of difficulty. Five classes were considered for this study. Suppose 15 students from each class were randomly selected, (4) is there a significant relationship between their level of difficulty and prelim scores? (5) is there a significant relationship between their level of difficulty and midterm scores? (6) is there a significant relationship between the extent of preparation and level of difficulty in their prelim scores?Is there an association between daily screen time and exercise habits in high school students?
