Answer:

The sample mean is 59

Explanation:

From the confidence interval given above, it can be said that the sample mean is between a lower limit of 56 and an upper limit of 62

Margin of Error (E) = (upper limit - lower limit) ÷ 2 = (62 - 56) ÷ 2 = 6 ÷ 2 = 3

Sample mean = lower limit + E = 56 + 3 = 59
