At a local veterinary office, 48% of dogs get their teeth cleaned, while 35% of cats get their teeth cleaned. Let po and be the sample proportions of dogs and cats at this veterinary office, respectively, who get their teeth
cleaned. Suppose 25 dogs and 32 cats from this veterinary office are selected at random to collect data on their
teeth-cleaning history
Which of the following is the correct calculation and interpretation of the standard deviation of the sampling
distribution of po-c?
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.003 from the true difference in proportions
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.017 from the true difference in proportions.
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.054 from the true difference in proportions.
O The difference (dogs - cats) in the sample proportions of those that get their teeth cleaned typically varies about
0.131 from the true difference in proportions.
