A chemist made eight independent measurements of the melting point of tungsten. She obtained the following sample: 3411.16, 3409.80, 3412.66, 3409.79,3410.76, 3409.77, 3411.80, 3409.78 degrees Celsius. a.Please check if she can use the data to calculate confidence interval? Please show all calculations. b.Use the Student’s t distribution to find a 95% confidence interval for the melting point of tungsten. c.Use the Student’s t distribution to find a 98% upper confidence bound of melting point of tungsten.
