Q Search this co TextRequest reports that adults 18-24 years old send and receive 128 texts every day. Suppose we take a sample of 25-34 year olds to see if their mean number of daily texts differs from the mean for 18-24 year olds reported by TextRequest. a. Select the null hypothesis we should use to test whether the population mean daily number of texts for 25-34 year olds differs from the population daily mean number of texts for 18-24 year olds. 1. Ho: u= 128 2. Ho: H 128 3. Ho: 4 > 128 Select your answer - Select the alternative hypothesis we should use to test whether the population mean daily number of texts for 25 - 34 year olds differs from the population daily mean number of texts for 18 - 24 year olds, 1. H: u# 128 2. H: u = 128 3. H: u> 128 - Select your answer - v b. Suppose a sample of thirty 25 - 34 year olds showed a sample mean of 118.6 texts per day. Assume a population standard deviation of 33.17 texts per day and compute the p-value. Round your answer to four decimal places. c. With a = 0.05 as the level of significance, what is your conclusion? Select your answer - v Ho. We- Select your answer - v conclude that the population mean daily texts for 25 -34 year olds differs significantly from the population mean of 128 daily texts for 18 - 24 year olds. d. Repeat the preceding hypothesis test using the critical value approach. The critical value(s) is(are) Select your answer Can it be concluded that the population mean differs from 128?

You may need to use the appropriate appendix table or technology to answer this question. According to the Vivino website, suppose the mean price for a bottle of red wine that scores 4.0 or higher on the Vivino Rating System is $32.48. A New England-based lifestyle magazine wants to determine if red wines of the same quality are less expensive in Providence, and it has collected prices for 65 randomly selected red wines of similar quality from wine stores throughout Providence. The mean and standard deviation for this sample are $30.15 and $12, respectively.   (d) Repeat the preceding hypothesis test using the critical value approach. State the null and alternative hypotheses. (Enter != for ≠ as needed.) H0:       Ha:       Find the value of the test statistic. (Round your answer to three decimal places.)   State the critical values for the rejection rule. Use  ? = 0.05.  (Round your answers to three decimal places. If the test is one-tailed, enter NONE for the unused tail.)…

A retail store started a new inventory system on January 1, 2019. The loss prevention manager compared the number of units that were missing from each month's inventory in 2018 with the number of units that were missing from each month's inventory in 2019. The results are provided in the table below. 2018 2019 87 7171 79 75 91 67 78 76 82 68 75 65 88 72 86 75 83 64 77 70 89 73 83 63 What conclusion could be made using the median and interquartile range from the data?     The median for 2018 is 83, which is greater than 70.5, the median for 2019. The interquartile range for 2018 is 9, which is greater than the interquartile range for 2019, 8. The median for 2018 is 6969, which is less than 82.5, the median for 2019. The interquartile range for 2018 is 8.5, which is the same as the interquartile range for 2019. The median for 2018 is 83, which is greater than 71, the median for 2019. The interquartile range for 2018 is 16, which is greater…

Suppose you are interested in testing whether the mean earning of men in California differs significantly from the mean earning of men in New York. If the number of men from California in the sample is 123 and the number of men from New York in the sample is 88, how many degrees of freedom are there?
