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!!!

Step-by-step explanation:
Answer:
a) Log ( 2 ) = 4t Log ( 83/80 )
b) 4.7 years
Step-by-step explanation:
Attached below is the detailed solution
<u>a) exponential statement in log form for an investment at 15% quarterly </u>
Log ( 2 ) = 4t Log ( 83/80 )
n = 4 , r = 15
<u>b) using change to base to find double time in yr </u>
Double time in yr
t = Log ( 2 ) / 4log ( 83/80 )
= 4.7 years
Answer: y = -x + 9
Step-by-step explanation:
First, to find the slope of the line we will use: (y₂-y₁)/(x₂-x₁)
Using the two points, we get: (8-1)/(1-8)
Simplify it: 7/-7
Finally, the slope is -1
We can now write: y = -x + b
Next we will plug in a point into the equation we have:
(8,1) --> 1 = -8 + b Then solve algebraically
b = 9
Then finish the equation:
y = -x + 9
