1. (This is textbook question 9.26) Consider a situation in which a random sample of 1000 adults is surveyed and the proportion that primarily buys organic vegetables is found. If a new random sample of 1000 adults is taken from the same population, explain whether each of the following would change: a. The population proportion, p. b. The sample proportion, . c. The standard deviation of . d. The standard error of . e. The sampling distribution of , including its shape, mean, and standard deviation.

Consider a situation in which a random sample of 1000 adults is surveyed and the proportion that primarily buys organic vegetables is found. If a new random sample of 1000 adults is taken from the same population, explain whether each of the following would change:

a. The population proportion.

b. The sample proportion .

c. The standard deviation of the sample proportion.

d. The standard error of the sample proportion.

e. The sampling distribution of the sample proportion , including its shape, mean, and standard deviation.

a. The population proportion, p will also not change.

b. There would be a change in the sample proportion.

c. The standard deviation of the sample proportion will change

d. The standard error of the sample proportion will change

e. The sampling distribution will not change

Step-by-step explanation:

a. Inasmuch there is no change in the population parameter, the population proportion, p will also not change.

b. Sample statistics vary from sample to sample, thus, there would be a change in the sample proportion.

c. The standard deviation of the sample proportion will change, since it depends on the new sample proportion.

d. The standard error of the sample proportion will change, since it depends on the new sample proportion.

e. The sampling distribution will not change with the new random sample since it is dependent on the population.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
