Find the probability of correctly answering the first 2 questions on a multiple choice test if random guesses re made and each question has 6 possible answers.
My answer is 1/36
Assume that the data has a normal distribution and the number of observations is greater than 50. Find the critical z value used to test a null hyphothesis.
1. alpha symbol = 0.05 for a two tailed test
my answer = +1.96
2. alpha symbol = 0.05 for a left tailed test
my answer = -1.165
3. alpha symbol = 0.1 for a two tailed test
my answer = +- 2.33
please let me know if my answers are one the right track. Thanks!!
Probably a typo, but alpha for a 1-tailed .05 test should be 1.645
I think you are on the right track.
