10) A child lives in a tall apartment building with windows that open on each floor facing the street. The child enjoys opening windows from varying heights and spitting on people as they walk below. They spit ten times from each height and record how often they hit their target. Assume there is no wind, everyone walks at the same uniform pace, etc. Their data is recorded in the table below.

Four paints are being tested for weight loss in an abrasion machine. These paints differ in the proportion of one basic ingredient. The abrasion machine can handle three paint panels at one time. Yield is measured in terms of weight loss in a fixed period of time and at a fixed speed of the machine. Four runs are made. Consider run as block. The data are stated in coded units.

An article published by the American Meteorological Society, gives a rating system used to classify Nor'easter storms that frequently hit New England which often cause havoc near the ocean. A severe storm has an average peak wave height of μ=16.4μ feet for waves near the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land off piers. Suppose that a reading of 32 waves showed an average wave height of x¯=14.3 feet. Previous reports of severe storms indicate that σ=3.5 feet. Does this information suggest that the storm is decreasing below the severe rating? Use α=0.01 to test the claim.What is the level of significance? State the null and alternate hypotheses. H0:H0:? p σ μ χ Select an answer < = ≠ > H1:H1:? μ p χ σ Select an answer ≠ > = <
