A university wants to determine the average final exam scores. They are hoping it is at least 75 points. A sample of 50 students has an average score of 73, with a presumed population standard deviation of 8 points. Construct a 95% confidence interval for the true mean score. What exam score creates the bound (cut-off point) for this interval? Round your answer to 2 decimal places

A professor wants to estimate the average score of her class in the final exam. She randomly selects 40 exams from her class of 200 students. The sample mean is 75 points, and the standard deviation is 8 points. Determine a 95% confidence interval for the average exam score of the class.

A sample of 50 students has a mean exam score of 78 with a standard deviation of 10. Construct a 95% confidence interval for the true mean exam score of the population.

The dean randomly selected 18 students who took the calculus final exam and looked at their scores on it. In this sample the mean was 75.5 and the standard deviation was 6.7. The population of exam scores has a distribution that is approximately normal. Construct a 95% confidence interval for the mean score of all students who took this exam. Round your answers to 2 places after the decimal point, if necessary. If it is not appropriate to construct a confidence interval in this situation, then enter "0" in both answer boxes below.
