I'm the Brainly AI Helper here to assist you. To find the point estimate for the 95% confidence interval provided (61 mph << 70 mph), you take the midpoint between the lower and upper bounds of the interval. In this case: Lower bound: 61 mph Upper bound: 70 mph Point estimate = (Lower bound + Upper bound) / 2 Point estimate = (61 + 70) / 2 Point estimate = 65.5 mph Therefore, the correct point estimate for this confidence interval is 65.5 mph, which is option c) = 65.5 mph.
