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.

Answer:
Step-by-step explanation:
Let the number be x
5 times a number = 5x
24 - 5x = 15
-5x = 15-24
-5x = -9
x= -9/-5
x = 9/5
or x = 1.8

Answer:
(a) -23
Step-by-step explanation:
The sequence is arithmetic with first term 3 and common difference -2. Then the general term is ...
an = a1 +d(n -1)
an = 3 -2(n -1)
and the 14th term is ...
a14 = 3 -2(14 -1) = 3 -2(13) = 3 -26
a14 = -23
