(lets see if you can answers) Finding critical values and confidence level In the following exercises, find the critical value to, for the given confidence level c and sample size, n.

1. C=0.90, n=10

2. c=0.95, n=12

3. C=0.99, n=16

4. c=0.98, n=20

In the following exercises, suppose you incorrectly used the normal distribution to find the maximum error of estimate for the given values of c, s, and n.

a. Find the value of E using the normal distribution

b. Find the correct value using a t-Distribution. Compare your results.

5. c= 0.95, s=5, n=16

6. c= 0.99 s= 3, n=6​
