Given:
μ = $3.26 million, averaged salary
σ = $1.2 million, standard deviation
n = 100, sample size.
Let x = random test value
We want to determine P(x>4).
Calculate z-score.
z = (x - μ)/ (σ/√n) = (4 - 3.26)/(1.2/10) = 6.1667
From standard tables,
P(z<6.1667) = 1
The area under the distribution curve = 1.
Therefore
P(z>6.1667) = 1 - P(z<=6.1667) = 1 - 1 = 0
Answer: The probability is 0.

Answer:
It is not accurate because only information from teenagers was used to make the claim.
Step-by-step explanation:
This is the correct answer because they only used the data that pertained to their teen readers. The magazine does not only have teen readers, but has many ages. The statement regarding internet use generalizes it to all readers, not just teens, therefore making its claim inaccurate because the scope of inference is not appropriate for the claim that was made.
