I think It would be C. Checking a prediction. Sorry if I’m wrong
A potential problem is that you are willing to accept a <u>5% </u>chance of being wrong if you reject the null hypothesis.
The significance level is the probability of rejecting the null hypothesis if it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that there is a difference when there is actually no difference. Rejecting the true null hypothesis results in a Type I error.
The smaller the value of α the more difficult it is to reject the null hypothesis. Therefore, choosing a low value for α can reduce the likelihood of Type I errors. The result here is that if the null hypothesis is false, it may be more difficult to reject using a lower value for α. The alpha value or statistical significance threshold is arbitrary. Which value to use depends on your field of study.

Answer:
220 ohms
Explanation:
I = V / R
0.25 = 110 / R
R = 110 / 0.25
R = 440 ohms
Equivalent resistance = 440 ohms
Resistance of single light bulb = Equivalent resistance / number of bulbs
= 440 / 2
= 220 ohms
