- The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.You may need to use the appropriate appendix table or technology to answer this question. An agency reports that 11.5% of workers in a particular country belonged to unions. Suppose a sample of 300 workers is collected to determine whether union efforts to organize have increased union membership. (a) Formulate the hypotheses that can be used to determine whether union membership has increased. H0: p = 0.115 Ha: p ≠ 0.115 H0: p > 0.115 Ha: p ≤ 0.115 H0: p ≤ 0.115 Ha: p > 0.115 H0: p ≥ 0.115 Ha: p < 0.115 H0: p < 0.115 Ha: p ≥ 0.115 (b) If the sample results show that 36 of the workers belonged to unions, what is the p-value for your hypothesis test? Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = (c) At ? = 0.05, what is your conclusion? Do not reject H0. There is insufficient evidence to conclude that there has been an increase in union…If a die is rolled 64 times.

- Calculate the Interquartile range (IQR) of the following: Minimum = 9 First quartile = 16 Median = 23 Third quartile = 29 Maximum = 36In hypothesis testing, the critical value is a. O b. always positive needed to calculate the significance level the same as the p-value O d. used to determine non-rejection-regionA SimAirlines aircraft that flies between BWI and San Diego airport has 100 seats, and there are two types of fares: full ($500) and discount ($300). Although there is an unlimited demand for the discount fare, demand for the full fare is estimated to be normally distributed with mean 24 seats and standard deviation 16 seats. To maximize the revenue generated from this flight, how many seats SimAirlines should protect for full-fare passengers?
- When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of 62.462.4 oz. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces). 66.5, 64.4, 64.6, 65.5, 66.3, 67.4, 66, 62.4, 65.9, 6266.5, 64.4, 64.6, 65.5, 66.3, 67.4, 66, 62.4, 65.9, 62 Use the α=0.01α=0.01 significance level to test the claim that the mean weight is higher with the enriched feed.
