  4. Rejecting the null hypothesis when it is actually false.
  1. A sample of 200 teachers showed that 157 of them have a home mortgage. Use significance level .01 to test the claim that more than 75% of teachers have a home mortgage. State the conclusion for this test.

  2. There is not sufficient evidence to support this claim
  3. There is not sufficient evidence to warrant rejection of this claim.
  4. There is sufficient evidence to warrant rejection of this claim.
  1. A random sample of 18 new born babies showed a mean weight of 3.4 kg and standard deviation 0.3kg. Use significance level .10 to test the claim that the mean weight of new born babies is less than 3.5kg. State the conclusion of this hypothesis test.

n hypothesis testing we set alpha, the significance level, which limits the likelihood of making a Type 1 error if the null hypothesis were true. When does a type 2 error occur? Give a real world example of a decision and explain what the null hypothesis, alternative hypothesis, type 1 and type 2 errors would be – which would be worse in this case: making a type 1 error or making a type 2 error?

For a two-tailed hypothesis test at the significance level alpha, the null hypothesis H0: μ = μ0 will be rejected in favor of the alternative hypothesis Ha: μ≠ μ0 if and only if μ0 lies outside the (1 - α) level confidence interval for μ. Illustrate the preceding relationship by obtaining the appropriate one-mean z-interval for the data below. Suppose the mean height of women age 20 years or older in a certain country is 62.8 inches.

Test the hypothesis with a significance level (alpha) of .05 that the climate has changed since industrialization. Suppose that the mean temperature throughout history is 52 degrees. During the last 30 years, the mean temperature has been 53 degrees and suppose the population standard deviation is 2 degrees. What can we conclude? Then construct a 95 percent confidence interval for the population mean.
