Answer 2

Answer:

We have 99% and 95% confidence interval to be

7.1241 Or 5.276

Step-by-step explanation:

Given that n = 13

Mean = 6.2

Standard deviation = 1.7

Therefore to construct confidence interval for 99% and 95%.

Z score for 95% confidence level is 1.96

We have that:

6.2 +/- 1.96(1.7/√13)

6.2 +/- 0.9241

6.2+0.9241 or 6.2-0.9241

7.1241 Or 5.276
