In a January 2019 poll conducted by the Pew Research Center, they asked a random sample of U.S. adults if they owned a smartphone. The results are shown in the following table by race.

a. What proportion in each race category owns a smartphone? 

b. Does there seem to be an association between race and whether someone owns a smartphone? 

c. Write out the null and alternative hypotheses for this study. 

d. Put the table of counts in the Multiple Proportions applet (make sure you click on Use Table). What is the value of the Mean Group Diff statistic? 

e. Do at least 1000 repetitions and find a p-value. 

f. Based on your p-value, write a complete conclusion. Be sure to include to whom you can generalize the result.
