Suppose u, and u, are true mean stopping distances at 50 mph for cars of a certain type equipped with two different types of braking systems. The data follows: m = 5, x = 115.1, s, = 5.05, n = 5, y = 129.2, and s, = 5.36. Calculate a 95% CI for the difference between true average stopping distances for cars equipped with system 1 and cars equipped with system 2. (Round your answers to two decimal places.) A USE SALT Does the interval suggest that precise information about the value of this difference is available? Because the interval is so narrow, appears that precise information is available.

Question
![Suppose \( \mu_1 \) and \( \mu_2 \) are true mean stopping distances at 50 mph for cars of a certain type equipped with two different types of braking systems. The data follows: \( m = 5 \), \( \bar{x} = 115.1 \), \( s_1 = 5.05 \), \( n = 5 \), \( \bar{y} = 129.2 \), and \( s_2 = 5.36 \). Calculate a 95% CI for the difference between true average stopping distances for cars equipped with system 1 and cars equipped with system 2. (Round your answers to two decimal places.)
( [Input Fields] )
Does the interval suggest that precise information about the value of this difference is available?
- ○ Because the interval is so narrow, it appears that precise information is available.
- ○ Because the interval is so wide, it appears that precise information is not available.
- ○ Because the interval is so narrow, it appears that precise information is not available.
- ○ Because the interval is so wide, it appears that precise information is available.
