You run a significance test to determine if the average salary of Americans is $35,000. You end up rejecting the null hypothesis. You then find that the actual average salary is somewhere between $25000 and $2700o. This is significantly lower than expected!
Which of the following best describe the analysis above?
- Both statistically significant and practically significant.
- Statistically significant, but not practically significant.
- Practically significant, but not statistically significant.
- Neither statistically significant nor practically significant.

Let average salary be μ
H 0 : μ = 35000
and
H 1 : μ 35000
The null hypothesis is rejected.
Therefore, it can be concluded that The average salary is not $35000. Therefore, it is statistically significant.
Again the actual average salary is between $25000 and $27000. Since the actual average salary is much less than what was considered and the difference has an effect in real life so it is practically significant.
Thus the analysis is both statistically and practically significant.
Therefore, first option is correct.

The US government is interested in understanding what predicts death rates. They have a set of data that includes the number of deaths in each state, the number of deaths resulting from vehicle accidents (VEHICLE), the number of people dying from diabetes (DIABETES), the number of deaths related to the flu (FLU) and the number of homicide deaths (HOMICIDE).
Your run a regression to predict deaths and get the following output: 
At alpha=0.05, what is indicated by the significance F in this problem? 
A. The regression model does not significantly predict deaths. 
B. The regression model significantly predicts deaths. 
C. Two of the four independent variables significantly predict deaths. 
D. Three of the four independent variables significantly predict deaths.

A study of the population of NUIG students showed that out of a sample of 155 students surveyed, 45 said they regularly cooked their own food during term time.Carry out a hypothesis test to determine if this gives evidence that more than 25% of the population of NUIG students regularly cooked their own food during term time, i.e test the hypotheses for true population proportion, H0: p= 0.25 versus Ha: p > 0.25, at significance level α = 0.05
Complete the test by filling in the blanks in the following:
An estimate of the population proportion is .The standard error is . (3 dec places)The distribution is (examples: normal / t12 / chisquare4 / F5,6).The test statistic has value TS=. (2 dec places)Testing at significance level α = 0.05, the rejection region is: greater than (2 dec places).There (is / is no) evidence to suggest that the true proportion of the population of all NUIG students who regularly cooked their own food during term time, p, is greater than 0.25.

A local business offers test-taking courses for students who are planning to take the Graduate Record Examination (GRE) as part of their graduate school applications. The business promises to produce student test scores that are above the national average. You collect a random sample of 75 local students who have taken the course and calculate that their average GRE score is 1630 with a standard deviation of 320. The average GRE score for all students in the nation is 1590. Conduct a significance test at a=.05 to answer the research question: Does the course significantly improve local student GRE scores?
What are the test requirements/assumptions for this significance test? Check all that apply.
-Random Sample
-Normal Sampling Distribution
-Interval-ratio variable of GRE scores
With an alpha of .05, what is your critical score?
