A popular uprising that started on January 25, 2011 in Egypt led to the 2011 Egyptian Revolution. Polls show that about 69% of American adults followed the news about the political crisis and demonstrations in Egypt closely during the first couple weeks following the start of the uprising. Among a random sample of 30 high school students, it was found that only 17 of them followed the news about Egypt closely during this time. (Source: Gallup Politics, Americans' Views of Egypt Sharply More Negative, data collected February 2-5, 2011).

A smoke alarm is supposed to make noise when there is a fire and stay silent when there is no fire. Designers of a smoke detector would use the following hypotheses: H0: There is no fire. HA: There is a fire. What is a Type II error in this scenario? Group of answer choices A Type II error is the smoke alarm making noise when there is no fire. A Type II error is the smoke alarm making noise when there is a fire. A Type II error is the smoke alarm remaining silent when there is a fire. A Type II error is the smoke alarm remaining silent when there is no fire.
conclude? do not own cars. What are the hypotheses and what do you sample of 144 employees and 6.14 A canning company agrees with their supplier of canning watermelons that a rate of 6% spoiled melons at the loading platform is reasonable. When the cannery takes a sample of 100 melons from a truckload delivered by the supplier and finds at least eight of them are defective, then the cannery returns the whole shipment. In your opinion was this a reasonable action? a. What is the decision rule that should be used? b. What is the probability of the Type I error? c. Explain the meaning of Type I and Type II errors in economic terms as they would be seen by each of the two parties, the canning company and the supplier.

The null and alternative hypothesis in symbols would be: O Ho:u 2 96.54 H1: µ 96.54 O Ho:p = 96.54 H1:p + 96.54 O Ho:p 96.54 O Ho:u = 96.54 H1:µ + 96.54 O Ho:p > 96.54 H1:p < 96.54 The null hypothesis in words would be: O The average price of all textbooks from the store is $ 96.54 O The proportion of all textbooks from the store that are less than 96.54 is equal to 50% O The average price of textbooks in a sample is $ 96.54 O The average of price of all textbooks from the store is greater than $ 96.54. O The average of price of all textbooks from the store is less than $ 96.54. Based on a sample of 80 textbooks at the store, you find an average of 110.14 and a standard deviation of 12.8.
