Answer:
The answer is below
Step-by-step explanation:
Given that:
Confidence interval (C) = 99%, mean (μ) = 19.5, standard deviation (σ) = 5.2, sample size (n) = 35
α = 1 - C = 1 - 0.99 = 0.01
α/2 = 0.005
The z score of α/2 (0.005) is the same as the z score 0.495 (0.5 - 0.005) which is equal to 2.576.
The margin of error (E) is given as:
![E=Z_\frac{\alpha}{2}*\frac{\sigma}{\sqrt{n} } \\\\E=2.576*\frac{5.2}{\sqrt{35} } \\\\E=2.264](https://tex.z-dn.net/?f=E%3DZ_%5Cfrac%7B%5Calpha%7D%7B2%7D%2A%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%20%7D%20%20%5C%5C%5C%5CE%3D2.576%2A%5Cfrac%7B5.2%7D%7B%5Csqrt%7B35%7D%20%7D%20%5C%5C%5C%5CE%3D2.264)
The confidence interval = (μ ± E) = (19.5 ± 2.264) = (17.236, 21.764).
The confidence interval is between 17.236 and 21.764.
Answer:
A and can I have brainliest
Step-by-step explanation:
Answer:
- The cabinets have the same base area.
- The cabinets may have the same base dimensions.
- The cabinets may have different base dimensions.
Step-by-step explanation:
The volume of a prism is the product of its base area and height. It doesn't matter whether the prism is right or oblique, and the shape of the base is immaterial.
Both the given prisms have the same volume and height, so their base areas must be the same. The dimensions of the base may be the same, but do not have to be the same.
