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.
