A random sample of 65 light bulbs had a mean life of Xbar = 1535 hours. Construct a 95% confidence interval for the mean life, μ, of all light bulbs of this type. Assume σ = 77 hours.

A) 1510 hr < μ < 1560 hr

B) 1516 hr < μ < 1554 hr

C) 1519 hr < μ < 1551 hr

D) 1521 hr < μ < 1549 hr

E) 1514 hr < μ < 1556 hr

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
