    Exclamation The Help Deni Pass Her Accounting and Statistics Classes Thread!!!

    Ok, I've been stuck for the past week trying to figure some of this stuff out and I've got to get it done since it's already late. I'll post my one accounting problem I need help with first, and then I'll post my stats problem in another post. I just need a push in the right direction because I am SO confused...and you guys helped me before and I trust you to help me out. So...here goes.

    This problem involves straight line amortization of a bond discount (it has it for a premium, too, but I can do that myself if someone can show me the basic procedure).

    Heathrow issues $2,000,000 of 6%, 15-year-bonds dated January 1, 2004, that pay interest semiannually on June 30 and December 31. The bonds are issued at a price of $1,728,224.

    1. For each semiannual period, compute (a) the cash payment, (b) the straight-line discount amortization, and (c) the bond interest expense.

    2. Determine the total bond interest expense to be recognized over the bonds' life.

    3. Prepare the first two years of an amortization table using the straight-line method. (I think I could figure this one out myself if nobody knows what this is talking about.)

    Statistics...

    A random sample of of 40 farming regions gave a sample mean of (sample mean x)= $6.88 per 100 pounds of watermelon. Assume that the standard deviation is $1.92 per 100 pounds.

    a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their watermelon crop. What is the margin of error?

    b) Find the sample size necessary for a 90% confidence level with maximal error of estimate E = 0.3 for the mean price per 100 pounds of watermelon.

    c) A farm brings 15 tons of watermelon to market. Find a 90% confidence interval for the population mean cash value of this crop. What is the margin of error? Remember, 1 ton is 2,000 pounds.

    Another stats...last one (for now, anyway).

    Let x be a random variable that represents assembly time for the Ford Taurus. The Wall Street Journal reported that the average asembly time if mu = 38 hours. A modification to the assembly procedure has been made. Experience with this new method indicates that the standard deviation is 1.2 hours. It is thought that the average assembly time may be reduced by this modification. A random sample of 47 new Ford Taurus automobiles coming off the assembly line showed the average assembly time using the new method to be (sample mean x)= 37.5 hours. Does this indicate that the average assembly time has been reduced? The level of significance is 0.01.

    a) State the null and alternative hypothesis. (I've got that written down somewhere around here.)

    b) What sampling distribution will you use? What is the value of the sample test statistic?

    c) Find or estimate the P-value.

    d) Based on a-c, will you reject or fail to reject the null hypothesis? Are the data statistically significant at 0.01?

    e) State your conclusions in the context of the application.


    I understand the basic concept of this one, but I think I'm making it out to be much harder than is really is.

    Do you still need help with these, ma'am? I just saw this thread. I'm worth ass at math, but my room mate is a raging genius at math, and Stats....

    She's taking a test online right now, but she said she's almost done and she'll come look at it when she is.

    Yay! Just an FYI with the stats projects...I get the basic concept of setting the problem up, I just need to know HOW you get a certain conclusion based on the result you get from the problem.

    Hopefully that makes sense!

    Doesn't make a damn word a sense to me. But then again....I get lost in my own house sometimes....it will probably make sense to the genius
    that lives on the other side of my bedroom wall.

    She found her notes and I e-mailed her the problems, she's looking over them to see if she can help.

    Room mate is working tediously on problems...

    She has a question about the first Stats problem.

    Do you know what the t value for a 90% confidence interval is?

    Uh...it doesn't say. It only says what I typed up- I think that's part of the reason I'm so confused!

    Um...wait! Is it the critical value thing? I see this chart and it says the critical value for 90% is 1.645.

    Erm...Okay, I don't understand any of this so I'm just going to copy and paste what she e-mailed back to me. She said she's not sure if it was what you were looking for but it was as much as she could pull outta her brain and notes and just tried to give you some sort of idea.....

    Ok, for the second one::
    mu= 38 hrs. (mean of population)
    sigma= 1.2 hrs. (standard deviation of population)
    n= 47 (sample size)
    x-bar= 37.5 hrs. (mean of sample)
    alpha = .01 (level of significance)

    a) Ho: mu= 38
    Ha: mu= 38

    b) I would use a t-test
    t = x-bar - mu / [sigma / sq. rt. (n)]
    with
    t = 37.5 - 38 / [1.2 / sq. rt. (47)]
    t = -2.85

    **c) I don't remember how to find the p-value...

    d) If the p-value is less than .01 (our alpha), we reject the null hypothesis...Therefore, the data shows the average assembly time has been reduced.
    If the p-value is greater than .01, our null hypothesis was supported...Therefore, there is not enough data to show that the average assembly time has been reduced.
    ^I'm a little iffy on these conclusions but I think this is about how it's supposed to be^

    And this is what she sent me back for the first one. Hope they are of some sort of assistance.

    n= 40
    x-bar= $6.88 per 100 lbs.
    s= $1.92 per 100 lbs.

    mu= true mean price of watermelon per 100 lbs.

    a) x-bar +/- t * [s / sq. rt. (n)]
    6.88 +/- (1.645) * [1.92 / sq. rt. (40)]

    (6.369,7.391)
    We are 90% confindent that the true mean price of watermelon per 100 lbs. is between $6.369 and $7.391.


    **I don't remember how to do margin of error...

    **b) I don't really remember how to do this one plus I have no idea what maximal error of estimate is...

    **c) And for this one...I'm not sure what to do here...all I was able to figure out was 15 tons = 30000 lbs. and I assume that you should divide that by 100 (since the rest of the problem talks about "per 100 lbs.) and that equals 300 lbs. but I don't know what to do with that number...

    Sorry I wasn't able to help more - half of my Stats notes from last year are missing...

    Yay! I was working it out on my own and that's what I was getting. Now if I can just figure out the rest...hmm...super BIG thanks, though! That helped me to know I was on the right track!

    If anyone comes upon this thread and is handy at accounting...I still need help with the problem from my first post!
