Consider a murder trial. Two states of nature: θ1=”Guilty”, θ2 =”Innocent”. Two actions for the jury: a1 =”Jail”, a2 =”Free”. The loss function is zero if the jury makes a correct decision. The loss is 5 if the jury let’s a criminal free but it is 10 if an innocent person is sent to jail. Data from DNA is available in the form of a statistical variable X with X|θ1 ∼ N(1, 1/4) and X|θ2 ∼ N(0, 1). Find the Bayes rule under the assumption of equal a priori probabilities. The Bayes rule sends the accused to jail if and only if,
(A) 0 < x < 1
(B) x > 3 4
(C) 1 3 < x < 1
D) 2 3 < x < 2
(E) 1 < x < 2

In Python. A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies.
Below is an example file along with the program input and output:
Input : test.txt
output : 3/4 1, 98 1, AND 2, GUARANTEED 1, INDEED 1, PERCENT 1, SUCCEED 1, WILL 2, YES 1, YOU 2
The code needs to read different files by name and also the count the amount of times or occurrence the word showed up and attach the number to the word like above.. The text file will say
"AND YOU WILL SUCCEED
YES
YES YOU WILL INDEED
98 AND 3/4 PERCENT"

The following program can be done all in the main method. It demonstrates that a TreeSet eliminates duplicates and is ordered.
Create a Random object with a seed of 5.
Create an ArrayList numAL of type Integer
Populate numAL with 10 numbers randomly selected from 0 to 6
Print out numAL
Create a TreeSet numTS of type Integer
Create an Iterator alIter from numAl and use it to add all the elements of numAL in numTS.
Print out numTS
Sample output:
ArrayList: [2, 4, 4, 0, 4, 0, 1, 5, 5, 5]
TreeSet: [0, 1, 2, 4, 5]

Please clearly state the step number next to the answers given, thank you!
A random sample of 12 supermarkets from Region 1 had mean sales of 72.4 with a standard deviation of 6.2. A random sample of 16 supermarkets from Region 2 had a mean sales of 78.3 with a standard deviation of 5.3. Does the test marketing reveal a difference in potential mean sales per market in Region 2? Let μ1 be the mean sales per market in Region 1 and μ2 be the mean sales per market in Region 2. Use a significance level of α=0.05 for the test. Assume that the population variances are not equal and that the two populations are normally distributed.
Step 1 of 4: State the null and alternative
hypotheses for the test.
Step 2 of 4: Compute the value of the t test
statistic. Round your answer to three decimal
places.
Step 3 of 4: Determine the decision rule for
rejecting the null hypothesis H0. Round your answer to
three decimal places. (e.g. Reject H0 if t or
|t| is < or > ___________)
Step 4 of 4: State the test's conclusion. (Reject
or Fail to Reject)
