Hypothesis Testing
A sample of size of n=43 has a mean of x̄=1.065116 and a standard deviatoin of s=0.706056713560371. Given a population mean of μ=1.072177, does the sample provide sufficient evidence that the actual population mean is not equal to 1.072177 at a 95% level of confidence?
New Example
- State the null hypothesis H0 and alternative hypothesis Ha.
- Determine the significance level (α) and appropriate distribution to use.
- Calculate the test statistic.
- Determine whether to reject or fail to reject the null hypothesis H0.
- State the conclusion.
