At the α = 0.01 level of significance, can you conclude that the mean tuition and fees for public institutions in California differs from $30,000?

1. State the null and alternative hypotheses and the type of test this is?

2. Compute the critical value and the value of the test t statistic. How many degrees of freedom are there? (Show the work so I cam compare it with my work to make sure I understand this assingment)

CV, Test T, and df

3. Compute the p-value

4. Do you reject or fail to reject the null hypothesis. Explain why. Use the α = 0.01 level of significance?

what is the conclusion?
