question 70

Multiple Choice

Provide an appropriate response.
-In a random sample of 60 dog owners enrolled in obedience training, it was determined that the mean amount of money spent per owner was $\$ 109.33$ per class. Assuming the population standard deviation of the amount spent per owner is $\$ 12$ , construct and interpret a $95 \%$ confidence interval for the mean amount spent per owner for an obedience class.

• A) (\$106.29, \$112.37); we are \(95 \%\) confident that the mean amount spent per dog owner for a single obedience class is between \(\$ 106.29\) and \(\$ 112.37\).
• B) (\$106.78, \(\$ 111.88 )\); we are \(95 \%\) confident that the mean amount spent per dog owner for a single obedience class is between \(\$ 106.78\) and \(\$ 111.88\).
• C) (\$106.23, \$112.43); we are \(95 \%\) confident that the mean amount spent per dog owner for a single obedience class is between \(\$ 106.23\) and \(\$ 112.43\).
• D) (\$106.74, \$111.92); we are \(95 \%\) confident that the mean amount spent per dog owner for a single obedience class is between \(\$ 106.74\) and \(\$ 111.92\).
