Answer:
<u>True Statements:</u>
"Kaylee's necklace can have 25 pieces of rotelle"
"Kaylee's necklace can have 10 macaroni noodles and 15 pieces of rotelle"
"Kaylee's necklace can have 1 macaroni noodle"
Step-by-step explanation:
First condition:
max pieces is 25
Checking the choices, we eliminate anyone having more than 25 pieces.
choice 1 - 26 piece NO
choice 2 - 25 piece OK
choice 3 - 25 piece OK
choice 4 - 25 piece OK
choice 5 - 1 piece OK
choice 6 - 25 piece OK
So we eliminate first choice. Now, 2nd condition is 15 macaroni or 50 rotelle, so that's 50/15 = 3.33 rotelle = 1 macaroni
We check each choice and convert macaroni to rotelle and make sure they are under 50
choice 2 - 25 rotelle, so OK
choice 3 - 10*3.33 + 15 = 48.3, under 50, so OK
choice 4 - 14*3.33 + 11 = 57.62, NOT OK
choice 5 - 1*3.33 = 3.33 rotelle OK
choice 6 - 16*3.33 + 9 = 62.28 rotelle , NOT OK
So finally, the statements that are TRUE are:
Choice 2, Choice 3, Choice 5
A sample of size <em>n</em> taken from a normally distributed population with mean <em>µ</em> and standard deviation <em>σ</em> has a sample mean of <em>µ</em> and standard deviation of <em>σ</em>/√<em>n</em>.
So the sample mean would still be 180.1, while the sample standard deviation would be 100/√94 ≈ 10.31.
