Question

the distrubution of the number of occurrences of the letter t on the pages of a book is found to be a normal distribution with a mean of 44 and a deviation of 18. If there are 500 pages in the book, which sentence mostly summerizes the data?

Answer 1

post up the choices?

Answer 2

The letter t occurs less than 26 times on approximately 170 of these pages.


The letter t occurs less than 26 times on approximately 15 of these pages.


The letter t occurs more than 26 times on approximately 420 of these pages.


The letter t occurs more than 26 times on approximately 80 of these pages.

Answer 3

so the occurance of t being 26 seems to be the common between all the solutions, so we need to just solve for the probability of when t=26

do you remember the 65-95-99.7 rule of standard deveiations?

Answer 4

No sadly I've never learned or heard of this before in math class

Answer 5

I gotta take off, but is this a statistics class or a math class?
