Question 1181816
<font color=black size=3>
Part A


Here's the original table
<table border = "1" cellpadding = "5"><tr><td></td><td>E-mail</td><td>No e-mail</td></tr><tr><td>Computer</td><td>73</td><td>17</td></tr><tr><td>No computer</td><td>22</td><td>138</td></tr></table>
Let's compute the row and column totals (eg: 73+17 = 90 in the first row)
<table border = "1" cellpadding = "5"><tr><td></td><td>E-mail</td><td>No e-mail</td><td>Total</td></tr><tr><td>Computer</td><td>73</td><td>17</td><td>90</td></tr><tr><td>No computer</td><td>22</td><td>138</td><td>160</td></tr><tr><td>Total</td><td>95</td><td>155</td><td>250</td></tr></table>
The question in part A is asking the percentage of shoppers who do <u>not</u> have computer access. We see that 22+138 = 160 people do not have a computer at home. 
This is out of 250 people surveyed.


Therefore, 160/250 = 0.64 = <font color=red>64%</font> of the shoppers do not have a computer at home.


Answer: <font color=red>64%</font>


============================================================


Part B


Use the table we made in part A. Specifically, the second table is the most useful here.


There are 95 people who have email (since 73+22 = 95) out of 250 shoppers total


95/250 = 0.38 = <font color=red>38%</font> of the shoppers have email. 


Answer: <font color=red>38%</font>
