Answer:

Step-by-step explanation:

Using the equation of line

y - y_1 = m(x - x_1)

y = mx + C

First first the slope of the equation

y = 9x - 4

Note: if two lines are perpendicular, their slope will be negative reciprocal

Slope = 9, but because it is perpendicular

m = -1/9

Using the equation

y - y_1 = m(x - x_1)

With the point (-9,-17)

x_1 = -9

y_1 = -17

y - (-17) = -1/9(x - (-9)

y + 17 = -1/9(x + 9)

y = -1/9(x + 9) - 17

Open the bracket.

y = (-x -9)/9 - 17

Lcm is 9

y = -x -9 - 153 / 9

y = -x - 162 / 9

Let's separate

y = -x/9 - 162/9

y = -x/9 - 18

y = -1/9x - 18

Therefore, the equation of the line is y = -1/9x - 18

You intend to estimate a population mean μ from the following sample. 26.2 27.7 8.6 3.8 11.6 You believe the population is normally distributed. Find the 80% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to twp decimal places.

Answer:

The Confidence interval = (8.98 , 22.18)

Step-by-step explanation:

From the given information:

mean = $\dfrac{ 26.2+ 27.7+ 8.6+ 3.8 +11.6 }{5}$
