Answer:
the mean is 5.8 and the median is 6
Step-by-step explanation:
if you multiply the test scores by their frequencies and then add up all those values, and then divide by the number of test scores, you get 5.8
for the median, you write out all the test scores in order from least to greatest and how many times they appear. then if you go to the middle of that number line, youll find the median

A department store buys 400 shirts at a cost of $9,600 and sells them at a selling price of $30 each.
Find the percent markup.
The percent markup is
%. (Round to the nearest whole number as needed.)
Answer:
The percent markup is 25%.
Step-by-step explanation:
Percent markup:
The percent markup is given by the difference in selling price and buying price multiplied by 100% and divided by the buying price.
A department store buys 400 shirts at a cost of $9,600
This means that the buying price is:
$9600/400 = $24
Find the percent markup.
Buying price: $24
Selling price: $30
30 - 24 = 6
6*100%/24 = 25%
The percent markup is 25%.

At a casino, people line up to pay $20 each to be a contestant in the follow- ing game: The contestant flips a fair coin repeatedly. If she flips heads 20 times in 20 mil a row, she walks away with lion dollars; otherwise she walks away with R 0 dollars
(a) Find the PMF of R, the reward earned by the contestant.
(b) The casino counts "losing contestants who fail to win the 20 million dollar prize. Let L equal the number of los- ing contestants before the first winning contestant. What is the PMF of L?
(c) Why does the casino offer this game?
Answer:
a)
P ( R = 20 million ) = 0.00000095367
P ( R = 0 million ) i.e. not winning = 0.99999904633
b) P ( L ) = ( 1 - p )^l * p
C)The casino offer the game because the expected revenue exceeds the winning
Step-by-step explanation:
P( winning ) = P ( getting 20heads in a row ) = 0.5^20 = 0.00000095367
a) PMF of R
P ( R = 20 million ) = 0.00000095367
P ( R = 0 million ) i.e. not winning = 0.99999904633
b) what is the PMF of L
L = number of loosing clients before winning
P( L = 0 ) = P i.e. if first contestant wins, if the second contestant win, L=1 repeat same process continuously
P ( L = 2 ) = ( 1 - p)^2 p
Hence the PMF of L
P ( L ) = ( 1 - p )^l * p where p = 0.5^20
C) The casino offer the game because the expected revenue exceeds the winning
we can prove this using the relation below
E( L ) = ( 1 - P ) / 1 - ( 1 - P )
= 1 / P - 1
where p = 0.00000095367 ( probability of winning )
Hence E ( L ) = 1048575
hence expected revenue before someone wins
= (1048575 + 1 ) * 20 = $20,971,520

A sales manager wanted to determine if increasing sales commissions by 5% would increase employee satisfaction. Her analyst determined the p-value was 0.04. (Use α = 0.05.)
Based on the above output, what is the correct conclusion for the Wilcoxon Signed Rank Test?
a. We do not have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
b. We do not have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
d. We have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
Answer:
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
Step-by-step explanation:
Pvalue is less than the alpha-level:
If the pvalue is less than the alpha-level, we have that there is sufficient evidence of the hypothesis for the population mean/median/standard deviation we are testing.
In this question:
Pvalue less than the alpha-level, so there is evidence that there is a difference in the population median. This means that the correct answer is given by option C.
The correct conclusion is: c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
The given parameters are:
[tex]\mathbf{p = 0.04}[/tex] --- the p-value
[tex]\mathbf{\alpha = 0.05}[/tex] --- the significance value or the alpha level
From the options, we understand that the test parameter is the population median
By comparison, the p-value (0.04) is less than the alpha level (0.05)
When the p-value is less than the alpha-level, then it means that there is enough evidence of the hypothesis for the population parameter that is being tested.
Since the p-value is less than the alpha level, then it means that there is enough evidence to show the difference in the population median.
Hence, option (c) is correct
