Suppose that a regulatory agency wants to propose that congress cut federal funding to a metropolitan area if that area's mean level of nitrogen oxides (nox) is unsafe—that is, if it exceeds 5.0 ppm. the agency gathers sample nox concentrations on 60 different days and calculates a test of significance to assess whether the mean level of nox is greater than 5.0 ppm. what is a type i error in this context? choose the correct answer from the following choices, and then select the submit answer button. believing that the mean level of nox is 5.0 ppm or less when it really is believing that the mean level of nox exceeds 5.0 ppm when it really does not believing that the mean level of nox exceeds 5.0 ppm when it really does believing that the mean level of nox is 5.0 ppm or less when it really is not

step-by-step explanation:

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
