Write an equation of a line with the given slope and y-intercept (8,1)m=-1/2

Ganezh [65]

Slope intercept form is y=mx+b
first plug in m
y=-1/2X + b
now plug in the point (8,1) for the x and the y
1=-1/2(8) + b

now you need to solve for b
simplify
1=-4+ b
add 4
5=b

now that you know b
you can plug it into the equation along with the m

so the answer is
y=-1/2X + 5

Suppose a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101

stepan [7]

Answer:

101, 3, 0.025, 0.7416

Step-by-step explanation:

Given that a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.

As per central limit theorem we have

a) Mean of sample mean = $E(\bar x) =\\ \mu =101$
