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...
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...
