Use 90, 95, or 99 levels of confidence. Provide the Critical Value, a sketch of the Critical Value, the Standard Error, and all formulas and calculations. Use technology for the sketch. Answer to question 9: The c-value is 2.021 and also added a picture of the confidence interval i got as the answer. Population mean: 10.6 Question I need answered is below: Design a hypothesis test for the mean. Pick the same c-value selected in question 9. Provide a sketch of your solution. Your sketch should include critical values, test statistics, and p-value. Use technology for the sketch. Provide all formulas and any calculations. Use technology to justify the p-value found. You may use any method covered in class.

Answer to question 9: The c-value is 2.021 and also added a picture of the confidence interval i got as the answer.
Population mean: 10.6
Question I need answered is below:
Design a hypothesis test for the mean. Pick the same c-value selected in question 9. Provide a sketch of your solution. Your sketch should include critical values, test statistics, and p-value. Use technology for the sketch. Provide all formulas and any calculations. Use technology to justify the p-value found. You may use any method covered in class.
![The 95% confidence interval is:
CI = x ±t(s,)
= 10.585 + 2.021(0.485)
= 10.585 + 0.98
