Answer:
Step-by-step explanation:
The correct answer is (A).
The sample proportion is \hat{p} = \frac{975}{1500} = 0.65
p
^
=
1500
975
=0.65 and the z* critical value corresponding to 95% confidence is 1.96. The standard error is \sqrt{\frac{0.65(0.35)}{1500}}
1500
0.65(0.35)
, therefore the expression that gives a 95% confidence interval for the proportion of all dog owners that would admit to taking more photos of their dog than their significant other is 0.65 \pm1.96 \sqrt{\frac{0.65(0.35)}{1500}}0.65±1.96
1500
0.65(0.35)
