The management of a soft drink company is interested in determining whether the proper amount of soft drink has been placed in 1-liter bottles at the local bottling plant. The bottling plant has informed the management that the population standard deviation for 1-liter bottles is 0.025 liter. A random sample of 100 1-liter bottles selected from this bottling plant indicates a sample mean of 0.995 liters. Use a one-sample hypothesis test to decide whether the mean amount in the bottles is different from 1.0 liters. Use a 0.05 level of significance.

a. State the null and alternative hypothesis for this problem.

b. Determine the sample test statistic value for this problem.

c. Determine the critical test statistic value for this problem.

d. What is your statistical decision for this problem?
