The Next Questions Are Based On The Following Information:
A company selling new econometrics computer software advertises that firms using this software obtain,on average during the first year,a yield of at least 10% on their initial investments.A random sample of 10 of the franchises that used the software produced the following yields for the first year of operation: 9.4,11.1,10.4,10.5,11.2,8.2,8.5,4.0,8.8,and 6.1.Assume that population yields are normally distributed.
-On the basis of a random sample the null hypothesis: H₀ : μ ≤ μ₀ is tested against the alternative: H₁ : μ > μ₀ and the null hypothesis is not rejected at the 10% significance level.Does this necessarily imply that μ₀ is contained in the 90% confidence interval for μ?
