Question

(1 point) Matt thinks that he has a special relationship with the number 1. In particular, Matt thinks that he would roll a 1 with a fair 6-sided die more often than you'd expect by chance alone. Suppose ? is the true proportion of the time Matt will roll a 1.

(a) State the null and alternative hypotheses for testing Matt's
claim. (Type the symbol "p" for the population proportion,
whichever symbols you need of "<", ">", "=", "not =" and
express any values as a fraction e.g. **p =
1/3**)

?0 =

?? =

(b) Now suppose Matt makes n = 50 rolls, and a 1 comes up 11
times out of the 50 rolls. Determine the P-value of the test:

P-value =

(c) Answer the question: Does this sample provide evidence at
the 5 percent level that Matt rolls a 1 more often than you'd
expect?

(Type: Yes or No)

Answer #1

Matt thinks that he has a special relationship with the number
6. In particular, Matt thinks that he would roll a 6 with a fair
6-sided die more often than you'd expect by chance alone. Suppose
?p is the true proportion of the time Matt will roll a 6.

Matt thinks that he
has a special relationship with the number 4. In particular, Matt
thinks that he would roll a 4 with a fair 6-sided die more often
than you'd expect by chance alone. Suppose pp is the true
proportion of the time Matt will roll a 4.

ulia thinks that she has a special relationship with the number
3. In particular, Julia thinks that she would roll a 3 with a fair
6-sided die more often than you'd expect by chance alone. Suppose
pp is the true proportion of the time Julia will roll a 3.
(a) State the null and alternative hypotheses for testing
Julia's claim. (Type the symbol "p" for the population proportion,

1. After viewing the film Back to the Future, Matt takes a nap
but has a disturbing dream. He sees himself 50 years into the
future, and his town has become a large city. Dozens of computer
businesses exist in the city. However, he is still selling only
1200 computers a year at his store. He observes that computer
prices are now $900 and his ATC is still $1000. His AVC is $750 and
his AFC is $250. In a...

Suppose someone has told you that he will pay you $500 if you
can roll a die and have it land on a 6. You both agree that you
will use a virtual die that can be found at this website. Be sure
to set it on one die, and not two. You are not certain that using a
die such as this virtual die is actually as fair as a normal
plastic die and want to justify for yourself...

1. Consider the following game. For 3 dollars I will allow you
to roll a die one time. In return, I will pay you the value of the
outcome if your roll. (e.g. you roll a 5 and I pay you 5 dollars.)

buy in).
(a) Create a probability distribution table listing the possible
values of X and their corresponding probabilities P(X).
(b) Calculate E(X), the expected...

Question 5 (1 point)
You are interested in getting an investment portfolio started
with any extra money you make from your part time job while also
going to school. While flipping through the latest edition of Money
magazine, you read an article that of a survey of magazine
