Answer:
Step-by-step explanation:
In Statistitics whenever we test a hypothesis for testing a statistic, we use confidence interval.
Confidence interval is on either side of an assumed value a margin of error
Margin of error is calculated as critical value * sigma/sqrt of n
Thus we find that whenever n increases, margin of error decreases, thus making confidence interval narrower and thus making probability for accepting null hypothesis a less value.
Thus we find that option C is right.
C. Increasing the sample size decreases the probability because σx decreases as n increases.
Answer: roughly 4.2593
Step-by-step explanation:
920/216
put the equation through a calculator
approx. 4.2593
Answer:
About 55.9 degrees
Step-by-step explanation:
The cosine of an angle is equivalent to the length of the adjacent side divided by the length of the hypotenuse. Therefore:
![\cos x= \dfrac{14}{25} \\\\x=\cos^{-1}\left( \dfrac{14}{25}\right) \approx 55.9](https://tex.z-dn.net/?f=%5Ccos%20x%3D%20%5Cdfrac%7B14%7D%7B25%7D%20%5C%5C%5C%5Cx%3D%5Ccos%5E%7B-1%7D%5Cleft%28%20%5Cdfrac%7B14%7D%7B25%7D%5Cright%29%20%5Capprox%2055.9)
