The process is monitored daily by taking samples of sizes n = 160 units. Suppose that today's sample contains 14 defectives. Determine a 88% confidence interval for the proportion defective for the process todayIn order to determine if weather conditions play a significant role in how a disease effects wheat, fields of wheat are exposed to this disease over three consecutive summers, 2002-2004. The fields are later rated on a scale of 0.0 (resistant) to 10.0 (susceptible) based on how the disease has infected the field. The results are shown below along with the ANOVA table. At the 95% confidence level, compare the mean scores across the three years. 2002 2003 2004 7 7.3 5 4.7 8 3 8 5 2 3.3 3.3 7 6.3 4.7 7.3 7 3.7 8 7 4.3 6. 7 4.3 2 6.3 6.7 ANOVA Source of Variation df MS Treatment 20.97333 2 10.48667 4.127165 Error 76.22667 30 2.540889 Total 97.2 32Use the order statistics approach to estimate a 90% confidence interval of 95.1% VaR for a sample size of n = 1000 observations drawn from a normal distribution with zero mean and variance one.SEE MORE QUESTIONSRecommended textbooks for youMATLAB: An Introduction with ApplicationsStatisticsISBN:9781119256830Author:Amos GilatPublisher:John Wiley & Sons IncProbability and Statistics for Engineering and th…StatisticsISBN:9781305251809Author:Jay L.
