Follow-up Question
A company selling home appliances claims that the accompanying instruction guides are written at a 6th-grade reading level. An English teacher believes that the true figure is higher and with the help of an AP Statistics student runs a hypothesis test. The student randomly picks one page from each of 25 of the company's instruction guides, and the teacher subjects the pages to a standard readability test. The reading levels of the 25 pages are given in the following table:

How did you get standard deviation of 1.388?
How did you get x bar 6.48?
In the given n = 25, but in getting the df your n = 30, why?
---------------------
YOUR ANSWER:
---------------------
YOUR ANSWER:
Given:
n = 25
arrow_forward
Step 2
x¯ = 6.48
σ = 1.388
t = x¯ - μσ/n = 6.48 - 61.388/25 = 1.729
df = n-1 = 29
=> P = 0.048
Yes, the P-value is between 0.01 and 0.05 indicating evidence for the teacher's belief.
