I have two Turing machines, T1 and T2, which accept languages L1 and L2, respectively. I want to make a Turing machine that accepts the difference T1 – T2, that is, the strings in T1 and not T2. Explain how I can do so using the current machines that I have.

Answer #1

--> T1 is the turing machine which accepts the language L1.

--> T2 is the turing machine which accepts the language L2.

--> suppose is the language which accepts the strings in L1 - L2

--> now Turing machine T3 can be constructed which accepts a string s if and only if T1 accepts and T2 rejects.

      Then T3 is turing machine for the language L1−L2.

    Suppose L1, L2, and L3 are languages and T1, T2, and T3 are Turing machines such that L(T1) = L1, L(T2) = L2, L(T3) = L3, knowing that T3 is recursive (always halts, either halts and accepts or halts and rejects) and both T1 and T2 are recursive enumerable so they may get stuck in an infinite loop for words they don't accept..

    Part B - Automata Construction Draw a DFA which accepts the following language over the alphabet of {0,1}: the set of all strings such that the number of 0s is divisible by 2 and the number of 1s is divisible by 5. Your DFA must handle all intput strings in {0,1}*. Here is a methodical way to do this: Figure out all the final states and label each with the shortest string it accepts, work backwards from these states to...

    A facility for bottling soft drinks uses two fill and seal machines. For quality control purposes, data is collected on these machines to determine if they are filling the soft drinks with the same amount of drink. Based on data from these two machines, they found that a 95% confidence interval for the difference in these machines, population means is (-2.5 mL, 0.3 mL). Using this data, the bottling facility would like to test if there is a difference in...
