  1. Nonconformities occur in glass bottles according to a Poisson distribution. A random sample of 100 bottles contains a total of 11 nonconformities.
    (a) Develop a procedure for testing the hypothesis that the mean of a Poisson distribution equals a
    specified value Hint: Use the normal approximation to the Poisson.
    (b) Use the results of part (a) to test the hypothesis that the mean occurrence rate of nonconformities is Lambda =0.15
    Use α = 0.01.

4-32 Nonconformities occur in glass bottles according to a Poisson distribution. A random sample of 100 bottles contains a total of 11 nonconformities. (a) Develop a procedure for testing the hypothesis that the mean of a Poisson distribution lambda equals a specified value lambda0 Hint: Use the normal approximation to the Poisson. (b) Use the results of part (a) to test the hypothesis that the mean occurrence rate of nonconformities is lambda=0.15. Use alpha=0.01.

The number of carbohydrates found in a random sample of 14 fast-food entrees has a mean of 44 carbs, standard deviation of 9.2. Is there a sufficient evidence to conclude that the variance differs from an established 100 carbs? Assume the variables are approximately normally distributed. Use the 0.01 level of significance. Include distribution drawing;include all steps. Use Traditional Method for hypothesis testing unless specified otherwise. Use correct rounding rule for final results!

A random sample of 16 values is drawn from a mound-shaped and symmetric distribution. The sample mean is 11 and the sample standard deviation is 2. Use a level of significance of 0.05 to conduct a two-tailed test of the claim that the population mean is 10.5. (a) Is it appropriate to use a Student's t distribution? Explain. Yes, because the x distribution is mound-shaped and symmetric and σ is unknown.No, the x distribution is skewed left.    No, the x distribution...

A random sample of n1 = 49 measurements from a population with population standard deviation σ1 = 5 had a sample mean of x1 = 8. An independent random sample of n2 = 64 measurements from a second population with population standard deviation σ2 = 6 had a sample mean of x2 = 11. Test the claim that the population means are different. Use level of significance 0.01.(a) Check Requirements: What distribution does the sample test statistic follow? Explain. The...

1.The sample mean is an unbiased estimator for the population mean. This means: The sample mean always equals the population mean. The average sample mean, over all possible samples, equals the population mean. The sample mean will only vary a little from the population mean. The sample mean has a normal distribution. 2.Which of the following statements is CORRECTabout the sampling distribution of the sample mean: The standard error of the sample mean will decrease as the sample size increases....

1 Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test the hypothesis that the proportion of one-person households exceeds 0.27. A random sample of 125 households found that 43 consisted of one person. The Census Bureau would like to set α = 0.05. Use the critical value approach to test this hypothesis. Explain. 2 Organizations are relying more and more on social-networking sites to research job candidates. According to...
