Question

Individual Practice: 1. Identify the appropriate test statistic to be used given the following: \( \mu=70, n=15, \bar{x}=97 \), and \( s=21.90 \). Then, compute for the test statistic. 2. Identify the appropriate test statistic to be used given the following: \( \mu=200, n=225, \bar{x}=250 \), and \( \sigma=35.90 \). Then, compute for the test statistic.

Solved by Expert Victor Salazar

Step 1

- Given: \( \mu = 70 \), \( n = 15 \), \( \bar{x} = 97 \), \( s = 21.90 \). - Since the sample size \( n \) is small (less than 30) and the population standard deviation is unknown, use the t-test. Show more…
