total number of patients is 50.

total number of dogs is

1.   percentage of patients that were dogs

2.   the formula of standard deviation is

    the formula of standard error is

    where, σ is standard deviation and n is sample size.

3.   the formula of marginal error is

    where, z is the value for desired level of confidence.

    the value of z at 90% confidence interval is 1.645.

4.   the value of z at 95% confidence interval is 1.96.
