Answer:
Part 1: The statistic
(1)
And the degrees of freedom are given by
Replacing we got
Part 2: P value
Since is a right tailed test the p value would be:
Comparing the p value we see that is lower compared to the significance level of 0.01 so then we can reject the null hypothesis and we can conclude that the mean for the four year college is significantly higher than the mean for the two year college and then the claim makes sense
Step-by-step explanation:
Data given
represent the mean for four year college
represent the mean for two year college
represent the sample standard deviation for four year college
represent the sample standard deviation two year college
sample size for the group four year college
sample size for the group two year college
Significance level provided
t would represent the statistic (variable of interest)
System of hypothesis
We need to conduct a hypothesis in order to check if the mean enrollment at four-year colleges is higher than at two-year colleges in the United States , the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We can assume that the normal distribution is assumed since we have a large sample size for each case n>30. So then the sample mean can be assumed as normally distributed.

The green zone in the image provided below
Step-by-step explanation:
<u>Venn Diagrams</u>
They are graphic representations of the relations between different sets. Each set (X for example), is represented as an oval, rectangle or any other closed figure. The inside area of that figure are the elements who belong to X. The outside of that figure is "not X", or the logical negation of X
This question doesn't provide any references or options to answer it, but I'm giving you some general content to help you with your particular case. Please find the relevant information in the image below.
It can be seen the set called X, another one called Y and the sample space called . Everything inside the oval X belongs to it, everything outside the oval X is NOT X, shown in green.
