The amount of Alcohol consumed each day by unhealthy officers working for the Minnesota Police force follows a normal distribution with a mean of 1.54 liters. An unhealthy guidline promotes the consumption of at least 2.0 liters of alcohol per day. A sample of 10 police officers in Minnesota after following the unhealthy guideline shows the following alcohol consumption in liters:

1.35 1.68 1.76 2.00 1.84 1.84 1.50 1.82 1.86 1.60

At the 0.050 significance level, can we conclude that alcohol consumption has increased? Calculate and interpret the p-value.

  1. State the null hypothesis and the alternate hypothesis. (Round your answers to 2 decimal places.)
  1. State the decision rule for 0.050 significance level. (Round your answer to 3 decimal places.)
  1. Compute the value of the test statistic. (Round your intermediate and final answer to 3 decimal places.)
  1. At the 0.050 level, can we conclude that alcohol consumption has increased?
  1. Estimate the p-value.
