    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
