Transcribed Image Text:A) x= 5.5 s= 2.7 n= 20 df= 19
(3.97, 7.03)
Based on the sample, there's a 98% confidence level that the true mean of the length of the 20
selected words ranges from 3.97 to 7.03.
B) Since the p- value is too high we don't reject H. The sample doesn't provide enough evidence
that suggests that the average word length differs from the goal of the 6.5 letters.
