    One-sample 't' statistic




    I'm back This is my last stats assignment for this semester and I have a few questions that I'm not sure about. I'll post each one in a new thread (and please bear with me, I'm half-asleep!)

    Q:

    The one sample t statistic for testing

    Ho: mu = 0
    Ha: mu > 0

    from a sample of n = 15 observations has the value t = 1.82

    a) What are the degrees of freedom?
    b) Give the two critical values t* from Table C that bracket t. What are the right-tail probabilities p for these two entries?
    c) Between what two values does the P-value of the test fall?
    d) Is the vaule t = 1.82 significant at the 5% level? Is it at the 1% level?


    a) 14
    b) 1.761 and 2.145
    .05 and .025
    c) .05 and .10 ?
    d) 5% it is 1% it is not ?

    Thanks in advance!

    everything else looks OK
