Really need help with this one please!

Attendance Quiz 2 Name: Due : 1/21/21 1. (Testing a claim about a Mean: o not known.) Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Data Set 14 in Appendix B lists measured reading levels for 12 pages randomly selected from J. K. Rowling's Harry Potter and the Sorcerer's Stone. The Flesch- Kincaid Grade Level measurements are summarized with these statistics: n =12, x=5.075, s=1.168 . Teachers at the West Park School District will not use the book unless the reading level for a typical page can be shown to be above grade 4. Use a 0.05 significance level to test the claim that the mean is greater than 4
