Step-by-Step Solution:
Step 1 of 3

STAT 2004 WEEK 12  Statistical hypotheses- Research questions we wish to test using statistical evidence. o Ex: It’s always windy in Blacksburg.  Suppose W represents wind speed in the US. W ~N(7,3) US US  Null hypothesis-  Blacksburg7 mph  Alternative hypothesis-  Blacksburg mph o The alternative hypothesis is what you think the truth is. The null hypothesis always includes an equal sign.  Writing hypotheses: o Make alternative based on what you want to show. o Make null the opposite.  Making a non 95% confidence interval: o Determine what the leftover or alpha level is o Determine the cutoff z-score (z*) using the z-table  Look it up and use it to determine x, the x, the cutoff  Summary of approaching these problems: o Create hypotheses o Set alpha level (given: use 0.5 if it is not given) o If the scenario is two sided (equals or not equal to)  Build a confidence interval from alpha, x bar, and the standard error  Is the null hypothesis  beyond the confidence interval  If yes, reject the null  If no, fail to reject the null o If the scenario is one sided (less than or greater than)  Build distribution as if null were true  Determine cutoff based on alpha, mu, standard error  Is your
