Answer:
0.070 is the standard error of the mean weight in estimating a confidence interval estimate
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 2.00 ounces
Sample size, n = 71
Alpha, α = 0.05
Population standard deviation, σ = 0.590 ounces
Formula for standard error =
![S.E=\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=S.E%3D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Putting values, we get,
![S.E = \dfrac{0.590}{\sqrt{71}} = 0.07002\approx 0.070](https://tex.z-dn.net/?f=S.E%20%3D%20%5Cdfrac%7B0.590%7D%7B%5Csqrt%7B71%7D%7D%20%3D%200.07002%5Capprox%200.070)
Thus, 0.070 is the standard error of the mean weight in estimating a confidence interval estimate
Answer:
64
Step-by-step explanation:
It is going up by 6
Answer:
2(3x+6), 6(x+2), and 3(2x+4)
Step-by-step explanation:
X-intercepts are where the parabola touches the x-axis so are the roots. (X^2)+4x-60=0 ; (x-6)(x+10) =0; x-6=0 so x=6 and x+10=0 so x=-10.
