A. Identify the tcritical of the following. (10 points) Confidence Tailed test Given Level 90% 95% 99 % 90 % Two-tailed One-tailed Two-tailed One-tailed df = 23 df = 12 n₁-8, n₂=15 n = 11 B. Solve the problems by following the step-by-step procedure in hypothesis testing. (10 points) 1. An investigator predicts that dog owners in the country spend more time walking their dogs than do dog owners in the city. The investigator gets a sample of 12 country owners and 15 city owners. The mean number of hours per week that city owners spend walking their dogs is 10.0. The standard deviation of hours spent walking the dog by city owners is 4.0. The mean number of hours, country owners spent walking their dogs per week was 12.0. The standard deviation of the number of hours spent walking the dog by owners in the country was 5.0. Do dog owners in the country spend more time walking their dogs than do dog owners in the city? Accomplish the table below: Dog Owners Country City A.
