Calculate the critical degrees of freedom and identify the critical t value for a single-sample t test in each of the following situations, using p=.05 for all scenarios. Then, state whether the null hypothesis would be accepted or rejected: 10) Two-tailed test, N = 10, t = 2.35 df= (answer) critical t = (answer) Accept or Reject Ho: (answer)
Determine how many degrees of freedom we have in a one-sample t-test for a sample size of N=26. (Hypothetical)
Below is the output from an ANOVA test Note that the degrees of freedom between groups is 2, The degrees of freedom within is given to be 39, the F statistic is given to be 3.33. and the p-value of 0.0461. (a) How many groups are there in this test? (b) What was the sample size? (c) What is the conclusion of the test at the 5% significance level? An independent random sample is selected from an approxi- mately normal...
1. Fill in the blank. In a one-sample t-test, we use the _________ to estimate the population standard deviation in order to calculate the standard error. How do you find the degrees of freedom (df) for a one-sample t-test? a. N b. Calculate the standard deviation of the sample c. n-2 d. n-1 Which of the following influences the likelihood of obtaining significant results? a. The larger your estimated standard error, the more likely it will be to get...
