A television network is deciding whether or not to give its newest television show a spot during prime happen, it will have to move one of its most viewed shows to another slot. The show they would rather watch. The network will keep its current lineup of shows unless the majority of the customers want to the new show. The network recelves 827 responses, of which 428 indicate that they would like to see the new show in the lineup....
(Round all intermediate calculations to at least 4 decimal places.) In order to conduct a hypothesis test for the population mean, a random sample of 15 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 8.6 and 1.8, respectively. Use Table 2 Use the p-value approach to conduct the following tests at a0.10 HO-us 7.3 against HA > 7.3 a-1. Calculate the value of the test statistic. (Round your answer...
(Round all intermediate calculations to at least 4 decimal places.) A local botter in Hawaii wishes to ensure that an average of 26 ounces of passion fruit juice is used to fill each bottle in order to analyze the accuracy of the bottling process he takes a random sample of 43 bottles. The mean weight of the passion fruit juice in the sample is 25 70 ounces Assume that the population standard deviation is 1 19 ounce Use Table 1...
(Round all intermediate calculations to at least 4 decimal places.) In order to conduct a hypothesis test for the population variance, you compute s2 = 68 from a sample of 12 observations drawn from a normally distributed population. Use the critical value approach to conduct the following tests at α = 0.05. Use Table 3. H0: σ2 ≤ 37; HA: σ2 > 37 a-1. Calculate the value of the test statistic. (Round your answer to 2 decimal places.)...
Round all intermediate calculations to at least 4 decimal places) Based on the are predictions of 47 members of the National Association of Business Economists INABE the US gross domestic product (GDP) will expand by 32% in 2011 The Wall Street Journal May 21.2010) Suppose the sample standard deviation of their predictions was 1% Al a 5% significance level test if the mean forecast GDP of all NABE members is greater than 3% a. Select the null and the alternative...
(Round all intermediate calculations to at least 4 decimal places.) An entrepreneur owns some land that he wishes to develop. He identifies two development options: build condominiums or build apartment buildings. Accordingly, he reviews public records and derives the following summary measures concerning annual profitability based on a random sample of 34 for each such local business venture. For the analysis, he uses a historical (population) standard deviation of $21,900 for condominiums and $19,600 for apartment buildings. Use Table 1....
In a recent Super Bowl, a TV network predicted that 67% of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, an advertising Group sampled 69 people who saw the commercials and found that 47 of them said they would watch one of the television shows. Suppose you have the following null and alternative hypotheses for a test...
(Round all intermediate calculations to at least 4 decimal places.) Consider the following hypotheses: H0: μ ≤ 24.1 HA: μ > 24.1 A sample of 60 observations yields a sample mean of 25.4. Assume that the sample is drawn from a normal population with a known population standard deviation of 5.9. Use Table 1. a. Calculate the p-value. (Round p-value to 4 decimal places.) 0.05 Picture p-value < 0.10 p-value Picture 0.10 p-value < 0.01 0.01 Picture p-value < 0.025...

(Round all intermediate calculations to at least 4 decimal places.) An entrepreneur owns some land that he wishes to develop. He identifies two development options: build condominiums or build apartment buildings. Accordingly, he reviews public records and derives the following summary measures concerning annual profitability based on a random sample of 33 for each such local business ventures. For the analysis, he uses a historical (population) standard deviation of $21,700 for condominiums and $20,000 for apartment buildings. (You may find...
