The error in the hypothesis test If a normal distribution of scores has a mean of 100 and a standard deviation of 10, what percentage of scores would lie above 2 standard deviations? A. 13% B. 2.15% C. 2.28% D. 97.97% Which of the following best describes the correct interpretation of a p-value resulting statistical test? A. The probability of an event occurring given that the null hypothesis is true B. The probability of an event occurring given that the alternative hypothesis is true C. The likelihood that you will reject the alternative hypothesis D. The likelihood that your sample calculation captures the true population statistic

Explanation / Answer

36.) (A) Exactly one hypothesis must be true

Reason In a hypothesis testing, we either

accept the null hypothesis, or when we reject the null hypothesis, alternative hypothesis is accepted.

37.) (C) Exactly two outcomes.

Reason Binomial distribution has exactly two outcomes with fixed probability, as in case of flipping of a coin. The outcome is either head or tails.

38.) (C) Significance level

39.) (B) 2.15%

40) (A) the probability of an event occurring given that the null hypothesis is true.
