the probability of making a Type I error is equal to the significance level of power. To increase the probability of a Type I error, increase the significance level. Changing the sample size has no effect on the probability of a Type I error.
The electricity of a take a look at can be expanded in a number of methods, for example increasing the pattern length, reducing the standard errors, increasing the difference between the pattern statistic and the hypothesized parameter, or growing the alpha degree.
The chance of creating a kind I mistakes is α, that's the extent of importance you put for your hypothesis check. An α of 0.05 indicates which you are inclined to accept a five% chance which you are incorrect whilst you reject the null hypothesis. To lower this risk, you have to use a decrease cost for α

Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
<u>The volume and the radius are given. (V=45π, r=3)</u>
<u>1. Solve for height</u>
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
<u>2. Plug the new radius (3*3=9) into this formula and solve for "V"</u>
V=π9²5
V=π81*5
V=405π
NEW VOLUME AFTER A TRIPLED RADIUS IS 405π

2:4 is the probability. It is more likely to receive a ordinary quarter, but the probability of the two headed quarter is still great enough to get it.
