Answer:
The 90% confidence level is 
Step-by-step explanation:
From the question we are told that
The sample size is 
The mean age is 
The standard deviation is 
Generally the degree of freedom for this data set is mathematically represented as
substituting values
Given that the level of confidence is 90% the significance level is mathematically evaluated as

10 %

Now 
Since we are considering a on tail experiment
The critical value for half of this significance level at the calculated degree of freedom is obtained from the critical value table as

The margin for error is mathematically represented as

substituting values


he 90% confidence interval for the true average age of all students in the university is evaluated as follows

substituting values


The next larger tenth is 10.1 .
The next smaller tenth is 10.0 .
10.04 is nearer to 10.0 than it is to 10.1 .
So the nearest tenth is 10.0 .
Answer: (2,0),(−2,0)
