A chemist made six independent measurements of the sublimation point of carbon dioxide (the temperature at which it changes to dry ice). She obtained a sample mean of 196.64 K with a standard deviation of 0.660 K. Section 05.02 Exercise 08.b - Find the confidence interval Use the Student’s t distribution to find a 98% confidence interval for the sublimation point of carbon dioxide. (Round the final answers to three decimal places.) The 98% confidence interval is ( , ).

A chemist made six independent measurements of the sublimation point of carbon dioxide (the temperature at which it changes to dry ice). She obtained a sample mean of 196.64 K with a standard deviation of 0.68 K. a) Use the Student's t distribution to find a 95% confidence interval for the sublimation point of carbon dioxide. b) Use the Student's t distribution to find a 98% confidence interval for the sublimation point of carbon dioxide. c) If the six measurements had been 196.35, 196.32, 196.4 198.02, 196.36, 196.39, would the confidence intervals above be valid? Explain.
