Suppose ? 1 and ? 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, x = 114.7, s1 = 5.04, n = 5, y = 129.9 and s2 = 5.37.

(a) calculate a 95% ci for the difference between true average stopping distances for cars equipped with system 1 and cars equipped with system 2.

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
