In​ baseball, League A allows a designated hitter​ (DH) to bat for the​ pitcher, who is typically a weak hitter. In League​ B, the pitcher must bat. The common belief is that this results in League A teams scoring more runs. In interleague​ play, when League A teams visit League B​ teams, the League A pitcher must bat.​ So, if the DH does result in more​ runs, it would be expected that league A teams will score more runs in League A park than when visiting League B parks. To test this​ claim, a random sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts​ a) through​ d) below.

A box encloses the vertical line segments, and horizontal line segments extend from both sides of the box to 0 and 12.

Does there appear to be a difference in the number of runs between these​ situations?

A. No but the number of runs scored in a League A park appear to be slightly higher than the number of runs scored in a League B park.

B. Yes because the number of runs scored in a League B park appear to have a higher median than the number of runs scored in a League A park.

C.Yes because the number of runs scored in a League A park appear to have a higher median than the number of runs scored in a League B park.

D.No because the number of runs scored in a League A park is about the same as the number of runs scored in a League B park.

​b) Explain why a hypothesis test may be used to test whether the mean number of runs scored for the two types of ballparks differ.

Select all that apply.

Continue? (y/n): n Bye!

Specifications

  • For the date/time of departure and arrival, the program should use the YYYY-MM- DD format for dates and the HH:MM AM/PM format for times.
  • Create a single data/time string variable based on the two input variables. Use this combined string variable to create a departure date-time object that will be used to determine the estimated arrival date and time.
  • For the miles and miles per hour, the program should only accept integer entries like 200 and 65.
  • Calculate the hours travelled based on the integer division of miles divided by mph. The minutes are based on the remainder of miles divided by mph. The remainder must then be converted to minutes based on the mph.
  • Assume that the user will enter valid data.

Should attorneys be allowed to use their discretion in selecting jurors? Does the risk of discrimination and jury manipulation that appears in the use of peremptory challenges outweigh the value of giving the attorneys discretion to exclude jurors who might be leaning toward the opposition? Can we have a system of fair trials without the peremptory challenge? Explain

In C++

Extra credit This is the formula for the future worth of an investment over time with consistent additional monthly payments and a steady rate of return. This can give you a bonus of 200 points. You will not be penalized if you do not do this nor will you be penalized if it is incorrect. This is a challenging problem because of all the mathematics involved. Let’s see how good you really are. FV = PV (1+ r/k) nk +PMT * [ (1+r/k) nk −1] * (1+ r/k) r/k FV : future value PV : initial value R : interest rate K : regular periodic investments • Annually, • Semi-annually, • Quarterly, • Monthly PMT: payment (installments) N : years Problem: You wish to start putting money away for your retirement (far-fetched, huh) anyway, how much would you have after 45 years if you started with an initial payment (PV) of $1000.00 and invested $250 (K) monthly. The dividend payments are 6% (R)and you invest $250 a month for the next 45 years. Your investment has an annual rate of return (R) of 6%.

Show how you would break this problem down into pieces (your pseudo code).

Then show your source code and display your initial investment, rate of return, length of time, monthly payments into the account and the final outcome. Show how much money you invested and what the final amount is, you’ll be surprised. HINT: try doing this problem manually first

Often organizations are faced with the necessity of changing the direction or focus of their organization – due to competition, due to new technology, due to environmental issues, regulations, etc. In these situations, uncomfortable changes are sometimes required.

a) Would younger or older employees be more likely to embrace change?

b) Would successful or less successful organizations be more likely to embrace change?

c) One element in reinforcing change within an organization is to replace people and hire outsiders. Even if done with a great deal of care and understanding, this can often come across as a somewhat cruel undertaking. Why is it necessary?

Subject - Religion 1100-005

Describe in a religion of your choosing a bit about its historical origins and how, from those origins, information about ultimate being is revealed to that religion’s followers. Especially note a founder and weather this revealing U.B. is primarily a prophet, a sage or an incarnation. Given such descriptions, what does one learn about the religion’s Ultimate Being? Is it more relational, more mysterious, more transcendent or immanent? Generally, show how the kind of origins we find in the religion’s history is coherent with its concept of ultimate being. You may also argue that the religion’s origins are not very consistent with its Ultimate Being concept.
