  1. For each shipment of parts a manufacturer wants to accept only those shipments with at most 10% defective parts. A large shipment has just arrived. A quality control manager randomly selects 50 of the parts from the shipment and finds that 6 parts are defective. Is this sufficient evidence to reject the entire shipment? Use a .05 level of significance to conduct the appropriate hypothesis. [15 Marks]

    QUESTION 17 Your instructor (Katie) believes that the average time of taking this exam is equal to 140 minutes. A sample of 4 students was taken and the following exam times were obtained. Assume the distribution of the population is normally distributed Sample: 150, 150, 180, 170 (Sample Std. Dev = 15) At a 0.1 level of significance, it can be concluded that the mean of the population is: a significantly less than 140 Ob not significantly different than 140...

    A manufacturer is comparing shipments of machine parts from two suppliers. The parts from Supplier A are less expensive, but the manufacturer is concerned they may be of lower quality than those from Supplier B. 700 parts were selected from Supplier A and 121 of them were found to be defective. 1200 parts were selected from Supplier B and 180 of them were found to be defective. Can we conclude at a 1% significance level that Supplier A has a...

    A surgical clamp manufacturer claims that only 10% of its parts are defective (p = 0.10). Hospital critics claim the defect rate is higher (p > 0.10). Testing of 500 randomly selected parts yields a Z statistic of -4.0. a & b) Write out the null and alternative hypotheses    c) Will the computation result in a one- or two-tailed test (on a Bell curve)? d) What does the negative z-score indicate regarding the critical region of the test (on a...

    Question 1 A study was conducted to estimate μ, the mean number of weekly hours that U.S. adults use computers at home. Suppose a random sample of 81 U.S. adults gives a mean weekly computer usage time of 8.5 hours and that from prior studies, the population standard deviation is assumed to be σ = 3.6 hours. A similar study conducted a year earlier estimated that μ, the mean number of weekly hours that U.S. adults use computers at home,...

    The quality-control manager at a compact fluorescent light bulb (CFL) factory needs to determine whether the mean life of a large shipment of CFLs is equal to 7,520 hours. The population standard deviation is 840 hours. A random sample of 49 light bulbs indicates a sample mean life of 7,340 hours. a. At the 0.05 level of significance, is there evidence that the mean life is different from 7,520 hours? b. Compute the p-value and interpret its meaning. c. Construct...
