Before microwave ovens are sold, the manufacturer must check to ensure that the radiationcoming through the door is below a specified safe limit. The amounts of radiation leakage(mW/cm?) with the door closed from 25 ovens are as follows (courtesy of John Cryer):15 9 18 10 5 12 85 8 1072 15 35 15 10 159 8 18 1 2 11а.Display the data in a dot diagramb. Determine P27, D6, Q2С.Use Chebyshev's theorem to interpret the interval u± 20

TEACHER Weatherwse is a magazine pubilished by the American Meteorological Soclety. One issue grves a rating system used to classity Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 40 waves showed an average wave height of x 16.7 feet. Previous studies of severe storms indicate that 35 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use 0.01.

E (6) (Round to two decimal places as needed.) = b. Find on. p (Round to four decimal places as needed.) c. What does the Central Limit Theorem say about the shape of the sampling distribution of p? O A. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will become approximately normal. OB. The Central Limit Theorem says that the shape of the sampling distribution of p is completely determined by the population parameter p. С. The Central Limit Theorem does not say anything about the sampling distribution of p because it is not a population mean. O D. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will approach the population…

Weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of u = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 36 waves showed an average wave height of x = 16.9 feet. Previous studies of severe storms indicate that o = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use a = 0.01. (a) What is the level of significance? State the null and alternate hypotheses. O Ho: H = 16.4 ft; H,: µ > 16.4 ft O Ho: H 16.4 ft; H,: µ = 16.4 ft (b) What sampling distribution will you use?
