Find a point estimate for the true difference in rollover

Reference no: EM13620263

Rollover rates for SUVs is a major transportation safety issue. In order to capture differences among true rollover proportions of SUVs made by COYOMA and HAMINDA, tests were performed on 100 SUVs made by COYOMA and 140 SUVs made by HAMINDA. The test resulted in 32 rollovers for COYOMA SUVs and 35 rollovers for HAMINDA SUVs.

A) Find a point estimate for the true difference in rollover proportions of SUVs made by COYOMA and HAMINDA.

b) Find a 95% confidence interval for the true difference in rollover proportions of SUVs made by COYOMA and HAMINDA.

c) interpret the confidence interval found in part b).
