For a study you find the sum of the squares is SS = 50 for a population of N = 10 scores. What is the variance for this population?

A population with a mean of µ = 9 has ΣX = 54. How many scores are in the population?

Around 70% of the scores will be located within two standard deviations of the mean.

Which of the following symbols identifies the population variance?

A population has µ = 30 and σ = 10. If 5 points are added to every score in the population, what are the new values for the mean and standard deviation?

Which of the following symbols identifies the sample standard deviation?

For a negatively skewed distribution, the mode is usually larger than either the median or the mean.

A client experiencing bradycardia is suspected of overdosing on diltiazem. Which treatment should the nurse anticipate being prescribed?

A client is diagnosed with chronic heart failure. Which drug classification should the nurse anticipate prescribed for the client?

A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.) Be sure to include your appropriate unit of measurement in your answer.
