can you please help me

"What percent of the time would you expect a" 

i'm not sure how is that related to hypotheses

daniellelovee · Answer

is not hypothesis is a statistics question about estimating means

ikram002p · Answer

hypothesis =given info

daniellelovee · Answer

no a hypothesis is an educated guess, regardless what I believe is that the answer is 5% because 2.5%(2)

daniellelovee · Answer

do you agree?

ikram002p · Answer

i agree that there are many meaning to hypothesis and the one i meant is "given" i shouldn't use that word lol but let go back to ur question i don't agree for 5%

daniellelovee · Answer

can you explain why you dont agree :)

ikram002p · Answer

we have 100 sample of Parma wallabies.
mean $\mu=46 ,\sigma=2.6$
now any value in the interval should be between  $46-\color{red}{2.6} $ and $46+\color{red}{2.6}$ agree ?

daniellelovee · Answer

wouldn't it be 2.5 instead of 2.6

ikram002p · Answer

well no as the interval should be
$(\mu-\sigma,\mu+\sigma)$

daniellelovee · Answer

ok so then it would be 43.4, 48.6

daniellelovee · Answer

my response has to be in percent btw
