They obtain a sample of 200 chocolate pudding packs and find that 72 of them contain less than 3.15oz of pudding! (even though 3.25oz is printed on the label.) a. (1 point) The packing company tells headquarters that the overall proportion of chocolate pudding packs containing fewer than 3.15oz of pudding is at most 25%. Dustin and Lucas think that more than 25% contain fewer than 3.15 oz of pudding. Perform the appropriate test at significance level . b. (1 point) The packing company now says that the overall proportion of chocolate pudding packs containing fewer than 3.15oz of pudding is at most 30%. Perform the appropriate test at significance level . c. (0.5 point) Repeat (1b) at significance level . What conclusion would you draw?

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
