Question

Determine if the following statements are true or false: If a given value (for example, the null hypothesis value of a parameter) is within a 95% confidence interval, it will also be within a 99% confidence interval. True Decreasing the significance level a will increase the probability of making a Type 1 error (i.e., rejecting H_0 when it is actually true). True The standard error of the sample mean, x|, would be larger for a sample size (n) of 25 than it would be for a sample size of 125. False

Explanation / Answer

1)true as 99% Confidence interval is wider then 95% confidence interval

2)false; as reducing it will decrease type I error

3) true as std error is inversely proporional to sample size
