Answer:
0.918 is the probability that the sample average sediment density is at most 3.00
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2.80
Standard Deviation, σ = 0.85
Sample size,n = 35
We are given that the distribution of sediment density is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
![=\dfrac{\sigma}{\sqrt{n}} = \dfrac{0.85}{\sqrt{35}} = 0.1437](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%20%3D%20%5Cdfrac%7B0.85%7D%7B%5Csqrt%7B35%7D%7D%20%3D%200.1437)
P(sample average sediment density is at most 3.00)
Calculation the value from standard normal z table, we have,
0.918 is the probability that the sample average sediment density is at most 3.00
The x-axis is usually the horizontal axis, while the y-axis is the vertical axis. They are represented by two number lines that intersect perpendicularly at the origin, located at (0, 0), as shown in the figure below.
The y-intercept is (0, 2), because it's the spot where the line crosses the y-axis. The other point showed on the graph is the x-intercept..
Answer:
Muscle strength is the ability to exert a maximal amount of force for a short period of time. ... Muscle endurance is the ability to do something over and over for an extended period of time without getting tired. In the gym, that may be doing 50 body weight squats in a row, moving to a rhythm.
Answer:
A. 40
Step-by-step explanation:
Angle A and angle S must be equal to one another, so add 45 and 55, subtract from 180, and divide that answer by 2
