Determine each statement is Type I error, Type II error, or no error. You reject the null hypothesis that the mean amount of soda in all cans of soda is at least 11 oz. The true mean is 11.07 oz. Suppose you fail to reject the null hypothesis that the mean lifetime of a battery is at least 50 hours. The true mean is 51.3 hours.  Suppose you fail to reject the null hypothesis that the mean diameter of a bolt is at most 10 cm. The true mean is 10.02 cm.

Question

Determine each statement is Type I error, Type II error, or no error.

  1. You reject the null hypothesis that the mean amount of soda in all cans of soda is at least 11 oz. The true mean is 11.07 oz.
  2. Suppose you fail to reject the null hypothesis that the mean lifetime of a battery is at least 50 hours. The true mean is 51.3 hours. 
  3. Suppose you fail to reject the null hypothesis that the mean diameter of a bolt is at most 10 cm. The true mean is 10.02 cm. 
Expert Solution
Step 1

You reject the null hypothesis that the mean amount of soda in all cans of soda is at least 11 oz. The true mean is 11.07 oz.

This means it is a rejection of a true null hypothesis. So this is a type I error.
