Jose wants to fence in his garden. The shape is a rectangle. Two sides are each 12 feet long. The other two sides are each 108 inches long. He buys 40 feet of fence. Part A What are steps he must take to see if he bought enough fence? Select all that apply. A. Convert both side lengths to the same unit. B. Find the area of the garden. C. Add 12 feet and 108 inches to find the perimeter of the garden. D. Compare the number of feet of fence he bought with the number of feet of fence he needs. Part B Did he buy enough fence? A. no B. yes

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.)
