In Chapter 1, we discussed the three major schools of theory in sociology. Name and briefly define two of these.

The nurse is evaluating parent-newborn bonding. Which action indicates positive bonding?

Which maternal behavior is characteristic of the “taking in” phase postpartum?

Which factor places a postpartum woman at risk for urinary retention?

A postpartum woman asks why she urinates frequently. The nurse explains that:

A nurse is teaching a new mother about umbilical cord care. Which statement indicates the need for further teaching?

(2 points) A fax machine dials a phone number that is typically busy 80% of the time. The machine dials it every 5 minutes until the line is clear and the fax is able to be transmitted. What is the probability that the fax machine will have to dial the number 9 times?

(4 points) Suppose it is known that 0.001% of the general population has certain type of cancer. A patient visits a doctor complaining of symptoms that might indicate the presence of this cancer. The doctor performs a blood test that will confirm the cancer with the probability of 0.99 if the patient does indeed have cancer. However, the test also produces false positives or says a person has cancer when they do not. The occurs with the probability of 0.2. If the test comes back positive, what is the probability that the person has cancer?

Simulate data with sample size 500 from an ARMA(1,2) process: 

True or False: The ACF values from the ACF plot for a given data provide unbiased estimates of the true autocorrelations for each lag h. Therefore we can rely on the sample estimate to reflect the real autocorrelation from the ACF plot even when h is approaching sample size n.
