The weight of discarded plastic from a sample of 62 households is xbar = 1.911 lbs and s = 1.065 lbs. a. Use a 0.05 significance level to test the claim that the mean weight of discarded plastics from the population of households is greater than 1.8 lbs.
b. Now assume that the population standard deviation sigma is known to be 1.065 lbs. Use a= 0.05 significance level to test the claim that the mean weight of discarded plastics from the population of households is greater than 1.8 lbs.

answer: 193

explanation:

200-7 = 193

its a i did it myself

step-by-step explanation:

question says to graph a triangle (xyz) and reflect it over the line y=x to create triangle x'y'z'.

we know that line y=x has both coordinates equal like (1,1), (5,5) etc so we can easily graph that reflecting line.

description of transformation:

we can see that x and y coordinate gets switched after transformation like (2,8) changed to (8,2)

what do you notice about the two line segments you drew:

we see that line segments xp and x'p are of same length and perpendicular to the reflecting line y=x.

do you think you would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line? :

yes, i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line.

how do you know? :

by measuring the length of yk and y'k.
