Given that
sample size = n = 30
Level of significance =
Here we want to calculate critical t value for one sample t test for a non directional hypothesis ( i.e. for two tailed hypothesis)
Degrees of freedom = n - 1 = 30 - 1 = 29
We get, Critical value = tc = 2.045................... (By using t table ) ............( ANSWER)
OR By using excel command
=TINV(Probability,Degrees of freedom)
=TINV(0.05,29)
= 2.045
tc = 2.045 .............( ANSWER)
Option B ) t critical is 2.045 is correct ............( ANSWER)

You have a sample size of N = 20. You will perform a one-tailed t-test with alpha = .05. You have looked up the critical value and it is -1.73. You have calculated t-test statistics of -1.41. Which of the following is correct? Reject the null or retain the null? You have a sample size of N = 37 and you are going to perform a one-sample t-test using alpha = .05. You go to the t-table and find that...
Consider an hypothesis test of two means with a test statistic t-stat = 0.78, a critical value t-crit = 2.07, and an hypothesized difference equal to 0. Using the information above, determine the number of standard errors your difference in sample means is away from zero. Select one: a. 0.78 b. 2.07 c. Cannot solve without a significance level. d. Cannot solve without knowing the sample size.
Question 8 3 pts The a two-tailed hypothesis test Is related to a confidence interval at the same level of alpha. All of the answers are true. Is expressed in a probability framework with a chance of being wrong in our conclusion. Has an alternative hypothesis that uses Not Equal in the expression For this problem you will need a t-table. What is the t-value needed for the critical value for a one-tailed upper hypothesis test with a sample size...
For this problem you will need a t-table. What is the t-value needed for the critical value for a one-tailed upper hypothesis test with a sample size = 33 and alpha =.01? Group of answer choices 2.449 2.738 2.733 2.445

1. 2. For this problem you will need a t-table. What is the t-value needed for the critical value for a one-tailed upper hypothesis test with a sample size = 40 and alpha =.05? 3. Each year Delta Dental does a survey of parents concerning the tradition of the Tooth Fairy. A random sample of 1,058 parents were asked about how much money they leave for a tooth and questions concerning how their child responded to the concept of the Tooth Fairy. In...
Hypothesis Testing Method A = ADKAR Framework (column A) Method B = Prosci Change Management Methodology (column B) Null hypothesis is H0: Method A = Method B Research (Alternative) hypothesis is H1:Method A < Method B Sample size: 30 One-tailed test: Direction stated in the hypothesis is determine more effective (greater or less than). Level of Significance (a): .05 t-test is used because standard deviation of population is unknown, sample size is less than 30 Cutoff Sample Score (critical value)...
