The weights in pounds of discarded plastic from a sample of 62 households yields the following statistics: 3 = 1.91 libs and S = 1.065 lbs. Use a 0.05 significance level to test the claim that the mean weight of discarded plastic from the population of households is greater than 1.500 lbs. b) CALCULATE THE TEST STATISTIC Oz= 3.96 Oz= -3.96 Oz= 0.0490 Oz= -3.04 Oz=3.04

Section 8.3: Testing Hypotheses. In Exercises 9-24, assume that a simple random sample has been selected and test the given claim. Unless specified by your instructor, use either the P-value method or the critical value method for testing bypotheses. Identify the null and alternative hypotheses, test statistic, P-value (or range of P-values), critical value(s), and state the final conclusion that addresses the original claim. 12.

The table shows the number of households burglarized in a sample of households with dogs and in a sample of households without dogs. Assume that you plan to use a significance level of α = 0.01 to test the claim that p_1<p_2p1<p2 Find the critical value(s) for this hypothesis test. Do the data support the claim that a smaller proportion of households with pet dogs are burglarized? Household with Dog Household without Dog Number of households in sample 209 117...

The average of the individual weights of garbages discarded by 17 households in one week have a mean of 35 lb. Assume that the standard deviation of the weights is 14.6 lb. Use α = .05 to test the claim that the population of households has a mean less than 33.22 lb, which is the maximum amount that can be handled by the current waste removal system. H0: HA: α= Z= p=
