The probability of this happening was (B) (I/1000)2-0000001 (C) 1 in a billion. (D) 3/10.Explanation / Answer
We always compare p - value with level of significance to determine the results.
Here the null hypothesis is that mean = 1 and if p - value will be greater than level of significance, Ho is not rejected and we will be able to conclude that the confidence interval will contain the hypothesized mean (Which in this case is 1).
For 95% confidence interval, level of significance = 5%
Since p - value < 5%, we reject Ho at 5% and hence, we can't conclude that the interval will contain 1.
At the same time,
For 99% confidence interval, level of significance = 1%
p - value > 1% so we do not reject Ho and hence, 99% confidence interval will contain 1.
Therefore,
Option C is correct.
