Management at Deluxe Diner is in process of establishing a quality control system for the time it takes to initially make contact with a table of patrons. A sample of size 3 istaken on each of the five different days.Suppose you calculated= 100 and R = 40. What is the 3-sigma UCL for the X-bar chart? Following the previous question, what is the 3-sigma UCL for the R chart?Less than 110Greater than or equal to 110 but less than 120Greater than or equal to 120 but less than 130Greater than or equal to 130 but less than 140Greater than or equal to 140 but less than 150Greater than or equal to 150

Sample size n = 3x¯¯=100R¯=40We have to find the 3σ UCL for the R-chart.

Let x represent the hemoglobin count (HC) in grams per 100 milliliters of whole blood. The distribution for HC is approximately normal with μ = 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 if the data indicates this patient has significantly high HC compared to the population. 14,19,16,14,19,19,14,21,17,17,14,17 Give the p-value and interpret the results. a) p = 0.0012; Based on 5% significance level, I will reject the null hypothesis and conclude this patient has a high HC level. b) p = 0.0012; 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) p = 0.0023; Based on 5% significance level, I will reject the null hypothesis and conclude this patient has a high HC level. d) p = .1053; Based on 5% significance level, I will fail to reject the null hypothesis and…
You wish to determine if there is a negative linear correlation between the age of a driver and the number of driver deaths. The following table represents the age of a driver and the number of driver deaths per 100,000. Use a significance level of 0.05 and round all values to 4 decimal places. Driver Age Number of Driver Deaths per 100,000 22 20 53 25 19 30 35 23 71 26 36 21 48 25 19 28 Ho: ρ = 0Ha: ρ < 0 Find the Linear Correlation Coefficient r = Find the p-value p-value = The p-value is Greater than αα Less than (or equal to) αα The p-value leads to a decision to Accept Ho Do Not Reject Ho Reject Ho The conclusion is There is a significant linear correlation between driver age and number of driver deaths. There is insufficient evidence to make a conclusion about the linear correlation between driver age and number of driver deaths. There is a significant positive linear correlation between driver age and number of driver deaths.…

lustration 19.33. An examination was given to 50 students at College A and to 60 students at Collage B. At A, the mean grade was 75 with S.D.=9. At B, the mean was 79 with SD=7. Is there a significant difference in the performance at the two Colleges at 5% level of significance?
23. A TV station claims to its advertisers that the mean number of minutes people view the station is 30. The station conducted a survey of 500 of their viewers who commute. The sample statistics are shown below. 29.11 Sx 20.718 A simulation was run 1,000 times based on the results of the survey. The results of the simulation appear below. 40 samples = 1000 mean = 29.101 SD = 0.934 30- 10 27.0 28.0 29.0 30.0 31.0 32.0 Time Based on the simulation results, is the claim that viewers watch the station for an average of 30 minutes plausible? Explain your response, including an interval containing the middle 95% of the data, rounded to the nearest hundredth. Frequency
