Answer:
If the observed sample mean is greater than 17.07 minutes, then we would reject the null hypothesis.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 15 minutes
Sample size, n = 10
Alpha, α = 0.05
Population standard deviation, σ = 4 minutes
First, we design the null and the alternate hypothesis
Since the population standard deviation is given, we use one-tailed z test to perform this hypothesis.
Formula:
Now,
Thus, we would reject the null hypothesis if the z-statistic is greater than this critical value.
Thus, we can write:
Thus, the decision rule would be if the observed sample mean is greater than 17.07 minutes, then we would reject the null hypothesis.
Answer:
A.) For the first inequality (y<=-3x+5) the ordered pairs are (0,5) and (1,2).
For the second inequality(8x-4y<24) the ordered pairs are (0,-6) and (1,-4).
B. (0,-7) is a solution to both inequalities.
C. (0,6) is not a solution to either inequality.
D. (0,0) is a solution for the first inequality, but not the second inequality.
