PROBLEM #1: WEEKEND CHORES A study claims that all adults spend an average of 8 hours on chores during a weekend. A researcher wanted to check if the claim is true. A random sample of 200 adults taken by this researcher showed that these adults spend an average of 8.2 hours on chores during a weekend with a standard deviation of 2.1 hours. Using the 1% level of significance, is the claim valid? What type of hypothesis describes the focus claim of the study?
