Nov 09, 2009 · b) Find the critical value and draw a normal curve. Z = -2.326. c) Find test statistics (write the appropriate formula, substitute the values, show excel formula, and calculate). I do think that this is written backwards, since (95-65)/95 is closer to 0.32 and would make for a more interesting question. Z = (phat-p)/sqrt(p*(1-p)/N)

Another approach to estimating the p-value would be to use a special t-table, such as http://www.columbia.edu/~dj114/t-table2.doc, which yields a p-value of somewhere between 0.3131 and 0.3481. A third, more precise method is to use the Excel function =TDIST(0.4714,12,1), which gives us …

Hypothesis Testing in Excel
For P-value work: the cutoff is tsam and the area is the P-value While TDIST lets you choose the number of tails that you’re talking about, TINV always deals with the area of the two tails, total. This means that if you want an area of α in the upper tail above the cutoff, you’re going to have to tell TINV that the total area in the two ...

In this version, the mean are so close that the null hypothesis that the mean for A is equal to the mean for B can’t be rejected, as indicated by the p-values of 0.40145 and 0.8029 for the one and two-tailed tests, respectively. Looking at Residuals from Regressions in Excel

Summary: To find the p-value for the hypothesis test for the difference in means, look in the column labeled “Sig. (2-tailed)” in the “t-test for Equality of Means” section, and in the second row (labeled “Equal variances not assumed”). Note that since the p-value given by SPSS is 2-tailed, you need to divide it in half for a 1-tailed test. In the above example the 1-tailed p-value would be .001.

d) A p-value below 0.05 is always considered sufficient evidence to reject the null hypothesis. e) A very low p-value provides evidence against the null hypothesis. f) A high p-value is strong evidence in favor of the null hypothesis. g) A p-value above 0.01 shows that the null hypothesis is true.

Thus we will compute p-value as well as the r-statistic. Again the standard is typically p> .05 or a 1-in-20 chance that the result is due to randomness. The larger the data sample the more likely you are to find a low p-value, even if the correlation is not very strong.
