The points {(-3, 2), (0, 1), (4,5)} are on the graph of function f. What are the coordinates of these three points after a horizontal stretch by a factor of 3, followed by a reflection across the x-axis?
© {-1-2,0-1, (3--)
O None of the given answers are correct.
O {(-9,-2).(0, -1).(12,-5)}
O {(-9,2), (0, 1), (12,5)]
O {(-3,-6), (0, -3), (4, -15)

Data on oxide thickness of semiconductors are as follows: 426 432 418 418 421 436 418 408 431 435 423 426 411 434 435 432 411 426 407 439 422 426 412 416 consider this data as a sample of the population. (a) calculate a point estimate of the mean oxide thickness for all wafers in the population. (round your answer to 3 decimal places.) (b) calculate a point estimate of the standard deviation of oxide thickness for all wafers in the population. (round your answer to 2 decimal places.) (c) calculate the standard error of the point estimate from part (a). (round your answer to 2 decimal places.) (d) calculate a point estimate of the median oxide thickness for all wafers in the population. (express your answer to 1 decimal places.) (e) calculate a point estimate of the proportion of wafers in the population that have oxide thickness greater than 430 angstrom. (round your answer to 4 decimal places.)
