Statistics question 12
Please show all steps and don\'t do in R and minilab.
Suppose we have conducted a t-test for the differences of mean X - Y , with (alpha) a = 0.10, and the Pvalue is 0.07. For each the following statements, say where the statement is true or false and explain why.
(a) We reject H0 with (alpha) a = 0.10.
(b) We have significant evidence for HA with (alpha) a = 0.10.
(c) We would reject H0 if a were 0.05 instead.
(d) The probability that x is greater than y is 0.07.
(e) There is a 7% probability that H0 is true.
(f) If H0 is true, the probability of getting a test statistic at least as extreme as the value of ts that
was actually obtained is 7%.
Solution
A) true ,because Pvalue <alpha
B)true ,becausse we have evidence to reject null hypothesis
C)False because P value > alpha=0.05
D) true,P value is based on obsrevational value
