Question

Name. Section 8.3 This Lab is to be worked in the Math Lab when an instructor is your own assignment to turn in. To receive credit for this as Due Date: man instructor is present. You may work with your classmates, but be sur receive credit for this assignment you must log in at least 2 hours each week. Testing Hypothe wang Hypotheses. In Exercises 9-24. assume that a simple random sample nas been selected and test the given claim. Unless specya test the given claim. Unless specified by your instructor, use either the Vatne method or the critical value method for testing bypotheses. Identify the null and alternative bypotheses, test statistic, P-value (or range of P-values), critical value(3), and state the final conclusion that addresses the original claim. 12. Discarded Plastic The weights (lb) of discarded plastic from a sample of households is listed in Data Set 23 in Appendix B, and the summary statistics are n = 62, X = 1.911 Ib, and s = 1.065 lb. Use a 0.05 significance level to test the claim that the mean w discarded plastic from the population of houscholds is greater than 1.800 lb. on standard deviation o is known to be 32. Repeat Exercise 12 assuming that the population stan

Answer 1

solution: Here, n= 62 x= 1911, 5= 1.065 Ko'os Hypothesis Hoi lu= 1.800 VIS H, u 1.8 Test statistic = Tuo slun 1.911-1.800 1.065 / 562 z = 0.8207 P value = 0.2059 Ssince using R = rnorm tabs > Proom Labs (z)) critical vcelue zonit = 22 = Zoos = 1.64 conclusion: first we decide to accept or reject Ho Decision Rule is 121 > Ecritical then we reject Ho 0.8207 1.64 so we reject Ho accept we accep Ho & conclude that we don't have sufficient evident to show that mean weight of plastic from the population of household grater than 1.8
