Answer:
Step-by-step explanation:
If the given is x^2 then the degree is 2.
Degree: 4 - x^2 = 2.
It is what is on the x to the highest power. If the question was
x^3 - 3x^2 + 2x + 4
The the degree would be 3
Number 7 you divide 6.48 by 4
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844
