The proportions of multiple samples of registered voters who vote are normally distributed, with a mean proportion of 0.38 and a standard deviation of 0.0485. what is the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39? use the portion of the standard normal table below to answer the question.

answer:

the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 is 0.1663 or 16.63%

step-by-step explanation:

we know that,

where,

z = z score,

x = raw score,

μ = mean = 0.38,

σ = standard deviation = 0.0485,

the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 is,

answer: idk

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
