Management of an airline uses a normal distribution to model the value claimed for a lost piece of luggage on domestic flights. The mean of the distribution is $600 and the standard deviation is $85. Suppose a random sample of 65 pieces of luggage is to be selected. a. What is the expected value of the average claimed value of the 65 pieces of lost luggage? b. What is the standard deviation of the sampling distribution of the sample mean claimed value of the 65 pieces of lost luggage? c. What is the approximate probability that the average claimed value of the 65 pieces is over $625?

The figure belоw displаys the first bаseline (tоp pаnel) frоm a multiple-baseline design in which the goal was to decrease the target behavior. The researcher collected data on the response during baseline for five sessions before introducing the intervention at session 6. Was the introduction of the intervention at this time the right thing to do to demonstrate experimental control? Explain using complete sentences.
