An independent-measures study uses n = 15 participants in each group to compare two treatment conditions. what is the df value f
AnnyKZ [126]

if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.

The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.

s2008m [1.1K]

Answer:

(A) depends heavily on a nationalized oil industry.

Explanation:

The problem with Venezuela, is that it is what economists called a rentier state. Basically, it means that the country heavily relies on the extraction of natural resources to generate revenue for its country.

With Venezuela, this natural resource is oil. Due to its overreliance on this resource, when oil price went down, the country's economy went down with it. Other countries in South America - such as Brazil and Argentina - diversify their country's source of income, creating a buffer when one sector is experiencing a crisis; which unfortunately Venezuela did not do.
