WEEK 6 TECHNOLOGY ASSIGNMENT
Hypothesis Test – Download the data set “Airport Speeds” in your preferred technology format (StatCrunch, Statdisk, Excel). Airport Data Speeds.xlsx Column 2 denotes the data speeds (Mbps) taken from 50 different airports for the carrier Verizon. Column 4 denotes the data speeds (Mbps) for the carrier AT&T from the same 50 airports.
Using technology (StatCrunch, Statdisk, or Excel) compute the mean data speed for each of the two carriers, Verizon and AT&T. Provide a printout of your technology output inside the body of your post (no attachments!) Based on this, which carrier do you think has the faster speed?
Next, complete a hypothesis test to test your claim about which carrier has the faster speed. Be sure to follow the 8-step procedure on page 376, using technology to do your calculations. You should include:
the null and alternative hypotheses (in English and in symbolic form)
your significance level
whether you are conducting a right-tailed, left-tailed, or two-tailed test
the p-value (calculated from technology)
your decision (meaning, whether you Reject or Fail-to-Reject the null hypothesis)
your conclusion in non-technical terms
Explain which test you conducted and why that is the appropriate test for this example. Explain your conclusion and how you arrived at that conclusion.
