In a random sample of 520 adults, the mean was 150 and the standard deviation was 4.5. the study was reported with a 95% confidence level, and the confidence interval for the study was 150 ± 0.39. what range of values shows the confidence interval for the study? 146.1 to 153.9 149.61 to 150.39 150 to 150.39 150 to 153.9

What range of values shows the confidence interval for the study?

149.61 to 150.39

A confidence level of 95% means:

95% of the time, population data will fall between 149.61 and 150.39.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

a .4y4

hope this !
