find the following confidence intervals

Near the beginning of the semester, you administered a survey to 10 students. Suppose we wanted to use your sample to calculate the mean age of college students. If your sample mean is 20.4 years and sample standard deviation is 1.27 years, then what are the following confidence intervals? (Round your answers to three decimal places.)

80% CI: LCL = years.

80% CI: UCL = years.

90% CI: LCL = years.

90% CI: UCL = years.

    Statistics Grades: The statistics grades in the fall semester had mean of 65. The SRS were taken from different statistics groups (A, B, C and D) considering that the total number of students that took part on the exam was 110. Assuming that the change in the grades has a normal distribution with standard deviation σ= 10, We computed a 90% confidence interval of the mean change in score μ in the population of all statistics students.
