It is suspected that the bags of French fries delivered to a fast food restaurant are lighter than what is specified in the supply contract. The manager of the restaurant would like to take a simple random sample of bags of French fries delivered and perform a statistic test to confirm that this is indeed the case. a. What would be the null and alternative hypothesis for this research? b. What is the type I error in this situation? c. What is the type II error in this situation? 2. Consider this hypothesis test: H0: 30 Ha: < 30 A simple random sample with size 80 provided a sample mean of 29.5. Assume that the population standard deviation is 2.4 a. b. c. d. e. Compute the test statistic. What is the pvalue? Using =0.05, what is your conclusion on the null hypothesis? Using =0.05, find the critical value. Specify the rejection rule using the critical value approach. What is your conclusion? 1. A simple random sample of 100 items is taken from an inventory and the average unit cost on the items is $25. The population standard deviation is known to be $5. 3. Test the hypothesis that the population mean is greater than $24.5 using the pvalue approach and a 0.05 level of significance. 4. Test the hypothesis that the population mean is different from $24.2. using the pvalue approach and a 0.05 level of significance. 5. Use =0.05 and the critical value approach to test whether the population mean is less than 26.2. 2. Consider this hypothesis test: H0: 12.5 Ha: > 12.5 A simple random sample with size 100 provided a sample mean of 13.1 and a sample standard deviation of 2.25. a. a. a. b. c. d. Compute the test statistic and its degree of freedom. What is the pvalue? Using =0.05, what is your conclusion on the null hypothesis? Using =0.05, find the critical value e. Specify the rejection rule using the critical value approach. What is your conclusion? 5. A simple random sample of 80 items is taken from an inventory and the average unit cost on the items is $23.4. The population standard deviation is not known. Instead the sample standard deviation s is also calculated from the sample and is found to be $5.2. a. Test the hypothesis that the population mean is greater than $22 using the pvalue approach and a 0.05 level of significance. b. Test the hypothesis that the population mean is different from $24.2 using the pvalue approach and a 0.05 level of significance. c. Use =0.05 and the critical value approach to test whether the population mean is less than $23.8. 6. Use 013Case.xls and the description of this file in Assignment 1 to answer this question. a. Perform a statistical test to see whether the average income of customers in the population is higher than $48,500. Use the pvalue approach and a 0.05 level of significance. b. Perform a statistical test to see whether the average age of customers in the population is less than 46.4. Use the critical value approach and a 0.05 level of significance? 7. Consider this hypothesis test: H0: p 0.45 Ha: p < 0.45 A simple random sample with size 500 provided a sample proportion of 0.41 a. b. c. d. Compute the test statistic. What is the pvalue? Using =0.05, what is your conclusion on the null hypothesis? Using =0.05, find the critical value.Specify the rejection rule using the critical value approach. What is your conclusion? 1. The proportion of female customers in a recent satisfaction survey of 500 listeners for a Toronto radio station is found to be 0.535. a. Test the hypothesis that the population proportion is greater than 0.5 using the pvalue approach and a 0.05 level of significance. b. Test the hypothesis that the population proportion is different from 0.55 using the pvalue approach and a 0.05 level of significance. c. Use =0.05 and the critical value approach to test whether the population proportion is less than 0.56. 2. Use 014Case.xls and the description of this file in Assignment 1 to answer this question. a. Perform a statistical test to see whether the proportion of male customers in the population is lower than 49.5%. Use the pvalue approach and a 0.05 level of significance. b. Perform a statistical test to see whether proportion of customers who would recommend the Credit Union to their friends before the pilot is greater than 0.61. Use the critical value approach and a 0.05 level of significance
