A researcher conducts an analysis of variance (ANOVA) to determine whether there are differences in exam grades among students using three different study strategies: re-reading the textbook and class notes (n = 44), taking practice tests available through the textbook publisher’s website (n = 39), or generating their own exam questions and practicing answering them (n = 39). The researcher calculates MSbetween = 225 and MSwithin = 40. The ANOVA reveals a significant treatment effect, but the researcher wants to quantify the size of the effect (eta squared). What percentage of the variance in exam scores was accounted for by the type of study strategy that students used? (Hint: Eta-squared is calculated as SSbetween/SStotal , so you will need to work backward from the MS values provided.)

Apply the selection-sort algorithm (shown in Figure 7.11) to sort the array containing the int-type numbers in Step 1 below. In the text box below, write from Step 3 on, with the numbers in the order that results from two numbers being swapped after the previous step, if a swap was necessary. Write your answers like the example Step 2. (5 points) Step 1: {73, 82, 12, 10, 62, 66, 1} Step 2: {1, 82, 12, 10, 62, 66, 73} (73 and 1 were swapped)

The nurse is caring for a client four hours after her first vaginal birth. She experienced instrumented delivery and has a second-degree laceration that has been repaired. She has an ice pack on her perineum and received ibuprofen for pain management one hour ago. She reports a pain level of 8 on a 10 scale in the perineal area and complains of rectal pressure. Her fundus palpates firm at the level of the umbilicus with a light amount of lochia rubra. The nurse prioritizes

A client is admitted to the ED with a blood pressure of 260/128 mm Hg. The client complains of headache and states that she is seeing double. She states she ran out of her Lisinopril and Metoprolol 3 days ago, and has not had the money to refill her prescription. Which of the following nursing interventions should the nurse expect to perform first? (Assume you have an order for all of the following.)
