The melting point of each of 16 samples of a certain brand of hydrogenated vegetable oil was determined, resulting in top enclose average of 94.32. assume that the distribution of melting point is normal with standard deviation 1.2. suppose a researcher suspects that the real mean melting point is not equal to 95. set up the hypothesis test in symbolic format.
for the same setting as problem 1, if the true mean is 94, the desired type one error is 0.05, type two error is 0.01, what is the minimum sample size?

its the fourth option

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

idk wbu

step-by-step explanation:

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
