The value for power can range between −1.0 and +1.0.

The greater the power, the more likely we are to correctly reject the null hypothesis, if it is incorrect.

Researchers typically sample with replacement, although the development of statistical theory was based on the use of sampling without replacement.

A researcher selects two samples of 64 participants each. In the first sample, the population mean was 10 and the variance was 16. In the second sample, the population mean was 25 and the variance was 9. Which sample will be associated with a larger standard error of the mean?

A main disadvantage of computing a range is that it takes into consideration only two values regardless of the number of scores in a distribution.

As a general rule, an interquartile range is a better estimate of variability than the IQR.

A researcher records the sound (in decibels) during a series of lessons taught by a substitute teacher at a local elementary school. In his study, he found that the sound was 80 ± 6 (M ± SD) dB. Assuming the data are normally distributed, which of the following is an appropriate conclusion?

Which of the following are functions of the hypothalamus? (Select all that apply.)

A nurse is noting from a client’s neurologic assessment findings that the client’s motor impulses are interrupted from the brain to the spinal cord. It also appears that the client lacks sensory impulses from the peripheral sensory neurons to the brain. Which area has the deficit?

The nurse learns a client was reported to have a history of basilar skull fracture with otorrhea. What assessment finding does the nurse anticipate?
