Johnson Filtration, Inc., provides maintenance service for water-filtration systems throughout southern Florida. Suppose that in addition to information on the number of months since the machine was serviced and whether a mechanical or an electrical repair was necessary, the managers obtained a list showing which repairperson performed the service. The revised data follow. Time bo + b₁ Months + b₂ Type + b3 Person Round your answers to three decimal places. bo b₁ b₂ b3 Repair Time in Hours 2.8 3.0 4.7 1.9 2.9 4.8 4.2 4.9 4.3 4.4 0000 Months Since Last Service 2 6 8 3 a. Develop the estimated regression equation to predict the repair time given the number of months since the last maintenance service, the type of repair, and the repairperson who performed the service. Assume that ₂ = 1 if the type of repair is electrical and 3 = 1 if Dave Newton performed the service.

Supposed that in the past, 10% of women in the Philippines have severe dysmenorrhea. Do we have enough reason to believe that the proportion of women having terrible cramps has decreased if, in a random barangay population of 1,256 women, 122 have severe enough cramping to interfere with their daily lives? Use a = 0.05
The Western community is composed of students, staff, and faculty. Students make up 55% of the Western community, staff make up 20%, and the rest are faculty. This past year 30% of students opted to get vaccinated for influenza, compared to 20% of staff and 90% of faculty. Based on this information what fraction of the Western community was vaccinated for influenza? Number (give at least five decimal places).
