Random Processes
... The t-distribution is like the normal distribution, but it takes the sample size into account. A t-table looks like the following: The left column is the degrees of freedom. This is the sample size minus one. The top tells you the probability level (the area to the left in terms) The table entries t ...

... Conclusion: Since t = -2.8 < -1.753, or say p-value < 0.01 < 0.05, we reject the null hypothesis. There is sufficient evidence to support the research hypothesis that the average body temperature is higher than 98.6 F. If the sample size is relatively large (>30) both z and t tests can be used for t ...
