Out of a sample 650 high school students, 321 take the bus to school every day. Construct a 99% confidence interval for the population mean of high school students that take the bus to school every day. A. CI=(43.23%,51.18%)
B. CI=(44.34%, 54.43%)
C. CI=(45.54%, 53.23%)
D. CI=(46.16%,52.16%)

now add them up : )

hoped i lol

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
