3P= 1/2 is an equation to represent the problem
Answer: 95% confidence interval would be (1341.2,1458.8).
Step-by-step explanation:
Since we have given that
n = 64
Average = 1400
Standard deviation = 240
We need to find the 95% confidence interval for SAT scores.
So, z = 1.96
So, Interval would be

Hence, 95% confidence interval would be (1341.2,1458.8).
