Jaden studies the life span of cats that are kept indoors versus cats that are allowed outside. his theory is that cats that live indoors have longer life spans than cats that live outdoors because they are not exposed to as many dangers. in his samples, the mean number of years a cat kept indoors lives is 10.3. the mean number of years a cat allowed to go outside lives is 7.4 years. assuming there are no outliers or skew, do the results support jaden's theory? select from the drop-down menus to correctly complete the statements. since the samples were large and randomly chosen, we can use the samples to understand the populations. because the sample mean for cats allowed to go outside is the sample mean for cats kept indoors, the results support jaden's theory.

Hi i’m not sure how to do question 20 if u could explain how to do it that’d b great

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
