Xintercept is where the line crosses the x axis or where y=0
yintercept is where the line crosses the y axis or where x=0
aka
finding the finding the x intercept is finding the x value when y=0
finding the finding the y intercept is finding the y value when x=0

y=-1/2x-5
xint
y=0
0=-1/2x-5
5=-1/2x
-10=x
(-10,0) is x intercpet

yint
set x=0
y=-1/2(0)=5
y=-5
(0,-5) is yint



xint: x=-10 or at point (-10,0)
yint: y=-5, or at point (0,-5)

You measure 25 turtles' weights, and find they have a mean weight of 31 ounces. Assume the population standard deviation is 12.8
Firlakuza [10]

Answer:

Margin of error = 4.21 ounces  

Step-by-step explanation:

According to the Question,

  • Given That, You measure 25 turtles' weights, and find they have a mean weight of 31 ounces. Assume the population standard deviation is 12.8 ounces

Therefore, Sample mean = 31 ounces  ,  Sample size(n) = 25 , Alpha(α) = 0.10 & Population standard deviation(σ) = 12.8 ounces

  • Thus, Margin of error  = Z_{critical} × σ / √n  (Z_{critical} at α=.010 is 1.645)

Putting The Values, We get

1.645 × (12.8 / √25 ) ⇒ 4.2112 ≈ 4.21

Thus, the maximum margin of error associated with a 90% confidence interval for the true population mean turtle weight is 4.21 ounces
