Express the confidence interval 35.9 pm 26.8 in interval form.

Answer 1

To express the confidence interval given as "35.9 pm 26.8" in interval form, you subtract and add the margin (26.8) from the central value (35.9).

1. Calculate the lower limit: \( 35.9 - 26.8 = 9.1 \)
2. Calculate the upper limit: \( 35.9 + 26.8 = 62.7 \)

Therefore, the confidence interval in interval form is \((9.1, 62.7)\).
