A factory's worker productivity is normally distributed. One worker produces an average of 72 units per day with a standard deviation of 21. Another worker produces at an average rate of 68 units per day with a standard deviation of 20. A. What is the probability that during one week (5 working days), worker 1 will outproduce worker 2? Note: I got an answer of .6685515, but it came up wrong. Please show work, I would really appreciate it.

The incubation time for Rhode Island Red chicks is normally distributed with a mean of 27 days and standard deviation of approximately 1 day. Look at the figure below and answer the following questions. If 1000 eggs are being incubated, how many chicks do we expect will hatch in the following time periods? (Note: In this problem, let us agree to think of a single day or a succession of days as a continuous interval of time. Assume all eggs...

The incubation time for Rhode Island Red chicks is normally distributed with a mean of 25 days and standard deviation of approximately 1 day. Look at the figure below and answer the following questions. If 1000 eggs are being incubated, how many chicks do we expect will hatch in the following time periods? (Note: In this problem, let us agree to think of a single day or a succession of days as a continuous interval of time. Assume all eggs...

4 . A machine makes spherical balls. Diameters X are normally distributed with mean 240.0 mm and standard deviation 3.0 mm. Another machine, working independently, makes sockets with diameters Y that are normally distributed with mean 249.0 mm and standard deviation 4.0 mm. A ball will fit into the socket only if ; otherwise the ball is too big for the socket. Define the “gap” to be the difference between the socket diameter and the ball diameter. Therefore a ball...

Suppose the heights of 18-year-old men are approximately normally distributed, with mean 69 inches and standard deviation 4 inches. (a) What is the probability that an 18-year-old man selected at random is between 68 and 70 inches tall? (Round your answer to four decimal places.) (b) If a random sample of nineteen 18-year-old men is selected, what is the probability that the mean height x is between 68 and 70 inches? (Round your answer to four decimal places.) (c) Compare...

To boost holiday sales, a jewelry store in Bismarck, North Dakota, is advertising the following promotion: “if more than 7 inches of cumulative snow fall on December 24, 25, 26, 27, and 28, you get your money back on all purchases made on December 17.” To
To boost holiday sales, a jewelry store in Bismarck, North Dakota, is advertising the following promotion: “if more than 7 inches of cumulative snow fall on December 24, 25, 26, 27, and 28, you get your money back on all purchases made on December 17.” To analyze this promotion, the stores manager has collected data and determined that snowfall over these five day period in December is normally distributed with the average of 6 inches and a standard deviation of...
