Which hypothesis suggests a change in indwelling catheter usage rates?

The alternative hypothesis is appropriate when suggesting a change in indwelling catheter usage rates because it specifically posits that there is a difference or an effect that is not due to chance alone. In this context, it indicates that an intervention, or some form of change, is expected to influence the usage rates of indwelling catheters.

In research, the alternative hypothesis often represents the research question itself, suggesting that the observed phenomenon is real and can be attributed to a specific factor or condition being analyzed. This hypothesis is essential for statistical testing, as researchers typically seek to provide evidence that supports this premise over the null hypothesis, which would state that there is no change or no effect.

In summary, by stating that a change in indwelling catheter usage rates is suggested, the alternative hypothesis effectively conveys the researcher's expectation that an intervention or certain conditions are likely to alter the current state of usage.
