Pick an activity or a person you would like to analyze (you can study yourself) for work sampling.

a) Create an observation schedule where you collect 27 observations in three days between the hours of 8:00am and 5:00pm.

b) Note the activities of the person at the 27 observation times found in part a.

c) Create a table summarizing the percentage time spent on each activity from part b. Would you recommend a possible improvement for this person to reduce non-value-added time?

d) If you wanted your maximum error to be 5% at a confidence level of 95%, how many observations should you have taken?
