A local bottler in Hawaii wishes to ensure that an average of 24 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 50 bottles. The mean weight of the passion fruit juice in the sample is 23.69 ounces. Assume that the population standard deviation is 0.87 ounce. . Calculate the value of the test statistic. - Find the p-value. c-1. What is...
A local bottler in Hawaii wishes to ensure that an average of 16 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 48 bottles. The mean weight of the passion fruit juice in the sample is 15.80 ounces. Assume that the population standard deviation is 0.8 ounce. (You may find it useful to reference the appropriate table: z table or t table)...

(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.) 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 television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. For this to happen, it will have to move one of its most viewed shows to another slot The network conducts a survey asking its viewers which show they would rather watch. The network will keep its current lineup of shows unless the majority of the customers want...
(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....
