Step 1
Collinear points are a set of three or more points that exist on the same straight line. Collinear points may exist on different planes but not on different lines.
Step 2
Graph the points; (-5,2),(0,6),(6,4)
Step 3
Conclude based on step 2
Since the points are not a straight line, we can conclude that the 3 points are not collinear.
Answer:
Set of hypothesis.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 20.5 oz
Sample mean, = 20.4 oz
Sample size, n = 50
Population standard deviation, σ = 2.25 oz
First, we design the null and the alternate hypothesis
We use One-tailed z test(left tailed) to perform this hypothesis.
Formula:
Putting all the values, we have
Based on the significance level, we can make our decision and complete the hypothesis testing.
We may accept the null hypothesis or fail to accept depending on different significance level.
