1. It is the probability distribution used when the population variance is unknown and/or if the sample size is small. A. chi distribution B. z-distribution C. t-distribution D. p-distribution 2. The t-distribution was developed by W.S. Gosset in 1908. Why was it called "Student's t-distribution"? 12. Wh A. because it was first introduced to senior high school students in 1908 B. because he was still a college student when he first introduces the t-distribution C. because he used the pen name "Student" when he introduces his paper about thet distribution D. because he used the students as samples in his study about the t-distribution 13. The 3. When do we consider that the sample size is small? A. when it is less than 30 B. when it is between 20 to 40 C. when it is greater than 25 but less than 40 D. when it is only 1% of the total population
