It is the aim of the Department of Health (DOH) to give measles vaccine to infants. When a barangay health worker in Casili, Mandaue City was asked by the City Health Officer of Mandaue City regarding the proportion of infants who received measles vaccine, the barangay health working claimed that 60% of infants had completed measles vaccine. On the basis of this claim, you as a City health personnel was tasked to verify this claim of the barangay health worker. You were able to interview 120 mothers. Seventy of these mothers confirmed that their children availed of the measles vaccine. You test the claim of the barangay health worker using 0.01 level of significance.
Prove that the mapping : F[x] →F(a)defined by h(x)=h(a) is a homomorphism.
soft drink dispenser is designed to dispense 250 mL of drink per cup. However, there have
been recent reports to the managements of a fast-food restaurant of both underfilled and
overfilled cups. Seeking to investigate this matter, they fill up 50 cups using this machine. If the mean amount of drink in the 50 cups is 248 mL with standard deviation of 12 mL, is there a
cause for concern for the management? Use a level of significance of 0.01

across the positively oriented surface S given by
->R(u, v) = 〈2u, 4v, −u^2〉, 1 ≤ u^2 + v^2 ≤ 4
Find the mass of the lamina in the shape of the portion of the plane with equation 4x + 8y + z = 8 in the first octant if the area density at any point (x, y, z) on the plane is δ(x, y, z) = 6x + 12y + z g/cm^2
In a test of Ho: u=80 against H1: u≠80, a sample of observations had a mean and standard deviation s=4.1. Find the p-value for the test.
