Clinical findings in patients who have hypernatremia would include:

When determining a plan of care for a patient with hypocalcemia, the nurse chooses which of the following as a high priority nursing diagnosis?

When testing the population correlation coefficient ρ, we calculate our sample test statistic t by using the formula t   =   r 1   –   r 2 n   –   2

Use the Flowchart for confidence intervals (one population).  Write all formula(s) used to calculate E and the corresponding confidence interval. In a random sample of n = 64 days in a recent year, the mean gas price was X = $4.35.  Assume the population standard deviation σ = $0.37.  Calculate the margin of error E and construct a 99% confidence interval for the population mean μ.  (10 points) CLT satisfied?  Why? E = ______________ (Two decimal places) ___________ < μ < ___________  (Two decimal places)

City Hospital has a temporary shortage of nurses, so nurses have been working overtime.  A random sample of six nurses reported that the number of overtime hours they worked last week were: 7,   2,   4,   5,   4,   3 Compute the mean for the data set.

Use the table of data below and the formula for grouped data to estimate the sample mean. Class Limits f x x*f x^2*f 0.5 – 1.5 2 1 2 2 1.5 – 2.5 4 2 8 16 2.5 – 3.5 5 3 15 45 3.5 – 4.5 8 4 32 128 4.5 – 5.5 7 5 35 175 5.5 – 6.5 3 6 18 108 TOTALS 29 21 110 474

A frequency table has class limits of 5 – 9, 10 -14, 15 -19, 20 -24, and 25 – 29.  The class width of each class is 4.

Merchants are always concerned when temperatures are extremely cold because they claim that they have fewer shoppers the colder it gets.  At Paradise Mall the merchant association did a study.  The results are contained in the table below.  Let x represent the noonday temperature in F and y represent the number of customers visiting the mall (in hundreds) that day. x 0 10 20 30 40 y 2 3 10 15 17 Calculate the correlation coefficient, r.

Ten equally qualified people apply for a job.  Three will be selected to interview.  How many different combinations of three people can be interviewed?
