Answer:
a) Expected value of the mean = 0.793 percent
b) Standard error = 0.019 percent.
Step-by-step explanation:
Given
mean = μ = 0.793 percent
Standard deviation = σ = 0.114 percent
a) The sample mean is related to the population mean through
μₓ = μ = 0.793 percent
Hence, the expected value of the sample mean = 0.793 percent.
b) The standard error is given as
Standard error = σ/√n
where n = sample size = 36
Standard error = (0.114/√36)
Standard Error = 0.019 percent.
Hope this Helps!!!
Answer:
That is a division equation.
Step-by-step explanation:
Step-by-step explanation:
3( x +1) = 5 (x - 2) + 7
3x + 3 = 5x - 10 + 7
5x - 3x = 3 + 10 - 7
2x = 13 - 7
2x = 6
Therefore x = 3
Her method will produce a valid sample.
Her method will produce a random sample.
Her method will produce a representative sample.
Answer:
- x^2+y
- 3(n-7)
- 37x-9.85
Step-by-step explanation:
1. If x represents a number, then x^2 represents its square. If y represents a second number, then the sum of that square and the second number is ...
x^2 + y
__
2. The difference of a number (n) and 7 is (n-7). Three times that difference is ...
3(n - 7)
__
3. If x represents a number, then the product of 37 and a number is 37x. 9.85 less than that is ...
37x - 9.85
