<h2>Answer with explanation:</h2>
Formula for plus-four confidence interval :
, where n= Sample size.
= Sample proportion and
z* = Critical z-value.
Let p be the proportion of puppies area found with early hip dysplasia.
As per given , we have
n= 42
Since confidence interval is not given , so we assume it as 95% .
z-critical value for 95% confidence is 1.96.
Then, the required confidence interval will become :
Hence, the plus four confidence interval for p = (0.0484, 0.256)
Interpretation: We are 95% sure that the true proportion of puppies area found with early hip dysplasia lies in (0.0484, 0.256).
if their base is the same, the exponents must also be the same for the equation to be true.
