Answer:
many buyers and sellers
Explanation:
Based on the information provided within the question it can be said that this situation violates the perfect competition assumption of many buyers and sellers. This is a model that many buyers and sellers in a competitive market agree on a single market price, and that no individual has influence over the price. Therefore if a single company, like Dell in this scenario, is able to influence the price then it is violating this assumption.

Answer:
Explanation:
Data given and notation
represent the sample mean
represent the standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to determine if the mean is lower than 5600, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
Answer:

Answer:
PERT ( Program Evaluation Review Technique)
Explanation:
PERT stands for Program Evaluation Review Technique. PERT charts are tools used to plan tasks within a project - making it easier to schedule and coordinate team members accomplishing the work.
PERT is a project management planning tool used to calculate the amount of time it will take to realistically finish a project.
Hence PERT is a technique to analyze and sequence tasks involved in completing a project, to estimate the time needed to complete each task, and to determine the minimum amount of time needed to complete each project
