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:
Suppose in 2010, the producer price index increases by 1.5 percent. As a result, the economists are most likely to predict that the consumer price index will increase in the future.
The producer price index is used in order to measure inflation from the perspective of costs to industry. Thus, the producer price index measures the cost of a group of goods and services which are purchased by firms.
Whereas the consumer price index refers to an average of the prices received by producers of goods and services at all the stages of the production process. Thus, when the producer price index increases by 1.5 percent, this is the indication that consumer price index will increase in the future.
Hence, higher producer prices means that consumers will pay more when they buy.

This scenario best illustrate Backward vertical integration
Explanation:
Backward integration is a vertical integration that extends the role of a organization to perform roles traditionally performed by firms in the supply chain.
