Answer:
In the picture attached, the graph is shown.
Step-by-step explanation:
No options are provided, so I made the graph.
The equation V = 4 + 2t, is the equation of a line with slope = 2 and y-intercept = 4.
To make a graph, mark some points is helpful. The next points are included in the graph:
t V
0 4 + 2(0) = 4
1 4 + 2(1) = 6
2 4 + 2(2) = 8
3 4 + 2(3) = 10
4 4 + 2(4) = 12
5 4 + 2(5) = 14
6 4 + 2(6) = 16
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.
