The formula for the confidence interval is given by
Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]
We have:
Sample mean = 23.95
n = 40
σ = 2.55
z* for 99% confidence = 2.58
Substitute these values into the formula, we have
23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91
So the lower interval is 22.91 and the highest interval is 24.99
It would be 1. You add all the temperatures. Get the sum and divide it by the amount of temperatures.
Answer:5p^3-2p^2-7p+1
Step-by-step explanation:
-3p^3+5p+(-2p^2)+(-4)-12p+5-(-8p^3)
open brackets
-3p^3+5p-2p^2-4-12p+5+8p^3
Collect like terms
-3p^3+8p^3-2p^2+5p-12p-4+5
5p^3-2p^2-7p+1
