Asample of 18 observations taken from a normally distributed population produced the following data:
28.5, 27.3, 25.3, 25.1, 31.1, 23.4, 25.5, 24.4, 28.1, 37.5, 23.6, 28.7, 27.6, 25.4, 27.5, 25.5, 22.7, 22.6

a. what is the point estimated μ?
b. make 95% confidence interval for μ
c. e=

i understand 100% 10/10 hit or miss?

step-by-step explanation:

345

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
