Answer:
Mean and standard deviation of the sample mean are 225.8 and 3.56 respectively.
Step-by-step explanation:
The mean (μₓ) and standard deviation of the sample mean (σₓ) are related to the mean (μ) and standard deviation of the population (σ) through the following relationship
μₓ = μ = 225.8
σₓ = σ/√n = 17.8/√25 = 17.8/5 = 3.56
Answer:
The 5th term is 16
Step-by-step explanation:
Given data
a= 12
say we want to find the fifth term
n=5
d= 1
The expression for the nth term given as
an = a + (n – 1) × d
Substitute
an= 12+(5-1)1
an= 12+4
an= 16
