Question

True of False is fine.

Each of the following statements is either true or false. Enter T or F into the space provided to indicate whether the statement is true or false. Just enterT or F, not the entire word. If a variable is normally distributed, then its sample means for samples of size n will also be normally distributed, even if n is small. A higher confidence level will result in a confidence interval that is narrower. A P-value tells us the probability that the null hypothesis is true given the data obtained from a sample. If the p.value is less than the significance level , the result is statistically significant. The margin of error in a confidence interval accounts for random sampling variation but does not account for variation due to flawed study design

Explanation / Answer

If a varibale is normally distributed, then its sample means for samples of size n will also be normally distributed even if n is small. True (T)

A higher confidence level will result in a confidence interval that is narrower. False (F) It wll result in a wider interval

A P-value tells us the probability that the null hypothesis is true given the data obtained from a sample. False (F)

If the P-value is less than the significance level alpha, the result is statistically significant. True (T)
