Answer:
Lines A and B form a consistent independent system
Step-by-step explanation:
we know that
A consistent system of equations has at least one solution
In this problem
The system of Line A and Line B has only one solution, since it has only one point of intersection.
and the Line A is different to Line B
therefore
Lines A and B form a consistent independent system
(independent because Lines A and B are different)
Answer:
A one-sided, two-sample t-test
Step-by-step explanation:
In the context, the values of the population standard deviations are not provided, therefore we have to use the two sample t tests for the difference between the two population means. This claim for the hypothesis or the alternative hypothesis is given as the average selling price is more for the first group of the sample size of 21 as compared to the other group of the sample size of 87. Therefore, we perform an one sided test or the upper tailed test.
