Answer:
a average of at least 70%
Explanation:
Answer:
D) If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.
Explanation:
Most of this AP question is fluff to confuse you, so make sure to emphasize the p-value and the actual question being asked.
For these interpretation problems, for chi-square GOF (goodness of fit) tests, the p-value is interpreted as such:
If the null hypothesis () is true, there is a [-value] probability of obtaining a chi-square () value of [test-statistic ] or more extreme.
This answer choice fits the format the best, and is therefore the correct answer.
It is possible to replace the CO2 cylinder in an inflatable PFD each time the PFD is inflated.
<h3>What is an inflatable PFD?</h3>
An inflatable PFD is a specific inflator mechanical device based on a CO2 cylinder that fills a given sac with air.
Inflatable PFDs need to have to maintaining different types of safety measures to avoid the failure of the device (especially in emergency situations).
Inflatable PFDs can be classified according to their features into Type I, Type II, Type III, and Type V (for example, Type III allows to buoy to more than 15 pounds), where Type IV PFDs are not inflatable.
In conclusion, it is possible to replace the CO2 cylinder in an inflatable PFD each time the PFD is inflated.
