Answer:
7 terms
Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. ... Examples of single terms: 3x is a single term.
Answer: Estimated standard error for the sample mean difference would be 1.
Step-by-step explanation:
Since we have given that
Mean of MD = 4.90
So, Sum of difference would be
![4.9\times 9=44.1](https://tex.z-dn.net/?f=4.9%5Ctimes%209%3D44.1)
S = 288
n = 9
We need to find the standard error for the sample mean differences.
Estimated standard error for the sampled mean difference would be
![\dfrac{\sqrt{Sum(D^2)-(\dfrac{sum(d)^2}{n})}}{n(n-1)}}\\\\=\dfrac{\sqrt{288-\dfrac{44.1^2}{9}}}{9(9-1)}\\\\=0.99\\\\\approx 1](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csqrt%7BSum%28D%5E2%29-%28%5Cdfrac%7Bsum%28d%29%5E2%7D%7Bn%7D%29%7D%7D%7Bn%28n-1%29%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%5Csqrt%7B288-%5Cdfrac%7B44.1%5E2%7D%7B9%7D%7D%7D%7B9%289-1%29%7D%5C%5C%5C%5C%3D0.99%5C%5C%5C%5C%5Capprox%201)
Hence, estimated standard error for the sample mean difference would be 1.
