We can use the table to put an upper bound on the p-value by noting that the largest value our test statistic value exceeds is 6.63. This says that our p-value < _____. Chi-Square Probability Calculator in JMP. To use this simply enter the test statistic value and the degrees of freedom (df) in the table and p-value will be calculated.

2If you do not enter a value for frequency after you enter the cash flow value, the calculator assumes a value of 1; however, the down arrow key must be pressed again before entering the next cash flow. You can also determine the NPV of the investment. Leave data entered and then enter the opportunity cost interest rate, say 8 percent.

D. Using Table A and df = 29, 0.0025< P-value < 0.005. Using the calculator and df = 53.64, P-value = 0.0023. Since in both cases the P-value is less than a = 0.01, we reject H 0. We have convincing evidence that Fern eats more, on average, when offered Tab-a-Cat than when offered Chow Lion.

“Significance” refers to the events and data that were actually observed, but which had small probability (P-value) according to the null hypothesis (so the null hypothesis is rejected as being incompatible with the data). Before proceeding to sample size estimation we need to review the basic concepts of hypothesis testing.

Using the above data, is there strong evidence (and if so, why) of a straight-line relationship between sales and profits? (a) Yes, because the slope of the least-squares line is positive. (b) Yes, because the P-value for testing if the slope is 0 is quite small. (c) No, because the value of the square of the correlation is relatively small.

Likelihood Ratio Chi-Square = 10.435, DF = 4, P-Value = 0.034. Minitab provides the (2 statistic, the number of degrees of freedom, and the P-value. The number of degrees of freedom for the (2 statistic is equal to The Minitab outputs shows that the (2 value is equal to 11.725, the degrees of freedom is equal to 4, and the P-value is equal to 0.02.

Gives you the raw data value which corresponds to a certain percentile. Ex: What is the cut off point for the highest 2% of heart-rates? Ans: invNorm(.98, 72, 8). 4. binompdf (n, p, X): Finds the probability of x number of successes in a binomial setting. 5. binomcdf (n, p, X): Finds the probability of x or fewer successes in a binomial setting.
