Question

Brayden tosses a coin 500 times. of those 500 times, he observes heads a total of 416 times. Calculations show that the probability of this occurring by chance is less than 0.01, assuming the coin is fair. Determine the meaning of the significance level Select the correct answer below: O We expect that 416 of every 500 coin tosses will result in heads. O At the 0.01 level of significance, the coin is likely not a fair coin O There is certainty that the coin is not a fair coin. O The results are not statistically significant at the 0.05 level of significance.

Answer 1

Answer

it is given that the probability of obtainining 416 heads out of 500 tosses is less than 0.01 significance level. This means that the result is significant and we can conclude that at 0.01 significance level, there is sufficient evidence to say that the coin is not fair.

option A is incorrect because we cant make prediction for every 500 coins

opton B is correct because at 0.01 significance level, the coin is not fair

option C is incorrect because we must tell about the significance level

option D is incorrect because when p value is less than 0.01, then this means that it is also less than 0.05

Answer 2

opton B is correct because at 0.01 significance level, the coin is not fair
