Question

sit 10. Which of the following statements are true? If false, T expiain briefly a) It is better to use an alpha level of 0.05 than an alpha Cl b) level of 0.01. b) If we use an alpha level of 0.01, then a P-value of 0.001 is st statistically significant. c) If we use an alpha level of 0.01, then we reject the null hypothesis if the P-value is 0.001. d) If the P-value is 0.01, we reject the null hypothesis for any alpha level greater than 0.01.

Answer 1

Solution:-

(a) -> Flase.

(b) -> True

significance level = 0.01, p = 0.001

p < 0.01 => statistically significant

(c) -> True

significance level = 0.01, p = 0.001

the p-valye is smaller than the significance level, then we reject the null hypothesis.

(d) -> True

P < alpha.
