Question: Explain what a P value is What is the criterion for
Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the P-value approach?
Relevant QuestionsSuppose we are testing the hypothesis H0: p = 0.3 versus H1: p > 0.3 and we ﬁnd the P-value to be 0.23. Explain what this means. Would you reject the null hypothesis? Why? To test H0: µ = 50 versus H1: µ < 50, a simple random sample of size n = 24 is obtained from a population that is known to be normally distributed. (a) If x̄ = 47.1 and s = 10.3, compute the test statistic. (b) If the ...To test H0: µ = 45 versus H1: µ ≠ 45, a simple random sample of size n = 40 is obtained.
