Question
Please explain answers for below. Thank you!
36. In a hypothesis test, a critical value of 0.01 as compared to a critical value of 0.05 would make it more difficult to reject a null hypothesis.
True or False
37. When testing a hyptohesis that the population from which a sample has been taken is equal to or great than a specific value, a two-tailed test is necessary
True or False
38. A two sample t test is conducted. The results show that the calculated p-value is 0.06. The critical p-value is 0.05. The null hypothesis should be rejected.
True or False
39. The compound value from a two sample t test measures how likely it would be to observe two samples this far apart that have been taken from the same population
True or false
40. Samples have been taken of a process before and after it has been improved. A two sample test is conducted. The null hypothesis states that the two means are not equal.
True or False
Explanation / Answer
Ans:
36)when p-value<=alpha,we reject null hypothesis.
Now,if alpha is decreased to 0.01,we will be less likely or more difficult to reject null hypothesis.
True
37)False(it will be one tailed test)
38)As,p-value=0.06>0.05,we fail to reject null hypothesis.
so,false
39)True
40)it will be dependent samples t test,where null hypotheis states that mean difference9before and after) is equal or greater than equal to or less than equal to 0.
False
