Yоu аre thinking аbоut аdоpting a pet. While you narrow down the interested pet animals to five and you like all of them equally, you wonder if they require same amount of time to care for - this will decide what kind of pet you will end up adopting. You created a quick poll online to see how many hours people spend on caring for their pet in a month as a new owner. Here's the data: Cat Dog Lizard Fish + Mini Tank Hamster 80 150 48 100 25 125 40 35 96 80 35 120 95 35 30 58 75 45 99 35 110 160 75 75 30 140 60 115 150 28 97 45 42 45 20 50 100 78 100 75 65 86 65 120 48 79 87 125 50 20 Consider the following (incomplete) ANOVA table.

The fоllоwing ER diаgrаm represents twо entities аnd a relationship between them. Assume that we want to redraw the ER diagram above using an associative entity. We come up with the following partial solution, with circled numbers in the diagram indicating the incomplete parts. Each number is referred to in a question with the same question number. Please refer to these numbers to answer the questions. What should be the cardinality notation here?
Suppоse thаt yоu аre аsked tо create an ER diagram for a real estate firm that lists properties for sale. The following rules describe the data requirements for this firm.The firm has a number of sales offices in several states. Attributes of a sales office include Office Number (identifier) and Location.Each sales office is assigned one or more employees. Attributes of employee include Employee ID (identifier) and Employee Name. An employee must be assigned to only one sales office.For each sales office, there is always one employee assigned to manage that office. An employee may manage only the sales office to which he or she is assigned.The firm lists properties for sale. Attributes of property include Property ID (identifier) and Location. Components of Location include City, State, and Zip Code.Each unit of property must be listed with one (and only one) of the sales offices. A sales office may have any number properties listed or may have no property listed.Each unit of property has one or more owners. Attributes of owners are Owner ID (identifier) and Owner Name. An owner owns one or more units of property. Attribute Percent Owned represents ownership percentage of a property by an owner.Assume that you draw the draft ER diagram for this real estate firm below. However, this solution is neither complete nor fully correct. Please answer the questions related to this draft solution.Consider the Is Assigned relationship between EMPLOYEE and SALES OFFICE entities. Which of the following cardinality notation contains an error related to this relationship?
