Consider a normal population distribution with the value of σ known. (a) What is the confidence level for the interval x − 2.81σ/√ n ≤ µ ≤ x + 2.81σ/√ n ? (b) What is the confidence level for the interval µ ≤ x + 2.00σ/√ n ? (c) What is the confidence level for the interval µ ≥ x − 1.96σ/√ n? (d) What value of zα/2 in the CI formula gives 99.7% confidence? (e) What value of zα/2 in the CI formula gives 75% confidence? (f) What value of zα would result in a 88% one-sided CI?

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
