Answer:
3308.5 thousands or 3,308,500.
Step-by-step explanation:
We have been given a formula that represented the number of incarcerated adults N (measured in thousands) in a certain country can be approximated by the equation where x is the number of years since 2000.
To find the number of incarcerated adults in 2013, we will substitute
in the given equation.
Since the number of incarcerated adults N is measured in thousands, so the value of N would be:
Therefore, 3,308,500 adults were incarcerated in 2013.
Answer:
P-value = 0.02275
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 12 kilograms
Sample mean, = 11.5 kilograms
Sample size, n = 4
Alpha, α = 0.05
Population standard deviation, σ = 0.5 kilograms
First, we design the null and the alternate hypothesis
We use one-tailed(left) z test to perform this hypothesis.
Formula:
Putting all the values, we have
We calculate the p-value from the standard z-table:
P-value = 0.02275
