1. Use the statement below to answer the following questions.

Laurence has a parakeet named Pudgie the Budgie. Laurence keeps a close eye on Pudgie's weight in order to monitor the overall health of his avian friend. Any deviation from Pudgie's ideal weight of 1.215 oz signals to Laurence that Pudgie is sick. Laurence weighs Pudgie every day, and every two months (60 days) he checks to see if Pudgie is at his ideal weight. It is the end of a two month period, and Laurence's measurements show Pudgie's weight over the past two months has an average of 1.247 oz and a standard deviation of 0.156 oz. Conduct a hypothesis test at the 90% confidence level to determine if Pudgie's weight has changed.

State the hypotheses (here are some needed symbols: )

H₀:

H₁:

The critical value is

The test statistic is

2.Using the information from the previous problem, state the conclusion for the hypothesis test. What does the conclusion of the test suggest about Pudgie's health?
