How to solve it

image text in transcribed
Let x represent the hemoglobin count (HC) in grams per 100 milliliters of whole blood. The distribution for HC is approximately normal with u = 14 for healthy adult women. Suppose that a female patient has taken 12 laboratory blood samples in the last year. The HC data sent to her doctor is listed below. We would like to know the data indicates this patient has significantly high HC compared to the population. 22, 17, 20, 17, 17, 14, 16, 21, 15, 21, 15, 22 Give the p-value and interpret the results. a) Op = .1053; Based on 5% significance level, I will fail to reject the null hypothesis and conclude this patient does not have a high HC level. b) Op = .0562; Based on 5% significance level, I will fail to reject the null hypothesis and conclude this patient does not have a high HC level. c) Op = 0.0003; Based on 5% significance level, I will fail to reject the null hypothesis and conclude this patient does not have a high HC level. d) Op = 0.0003; Based on 5% significance level, I will reject the null hypothesis and conclude this patient has a high HC level. e) Op = 0.0005; Based on 5% significance level, I will reject the null hypothesis and conclude this patient has a high HC level. Question 14 You did not answer the question. An important problem in industry is shipment damage. A windshield factory ships its product by truck and determines that it cannot meet its profit expectations if, on average, the number of damaged items per truckload is greater than 11. A random sample of 15 departing truckloads is selected at the delivery point and the average number of damaged items per truckload is calculated to be 11.3 with a calculated sample of variance of 0.64. Select a 90% confidence interval for the true mean of damaged items. a) O [-0.3635, 0.3635] b) [10.64, 11.36] c) [10.68, 11.92] d) [53.67, -33.86] e) [10.94, 11.66] f) ONone of the above
