Theresufficient evidence to support the claim that thefatality rate is higher for those not wearing seat belts.b. Test the claim by constructing an appropriate confidence interval.The appropriate confidence interval is < (P1 - P2) A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2888 occupants not wering seat belts, 31 were killed. Among 7856occupants wearing seat belts, 11 were killed. Use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. Complete parts (a) through(c) below.a.

Penalty Shots in World Cup Soccer A study¹ of 138 penalty shots in World Cup Finals games between 1982 and 1994 found that the goalkeeper correctly guessed the direction of the kick only 41 % of the time. The article notes that this is "slightly worse than random chance." We use these data as a sample of all World Cup penalty shots ever. Test at a 5 % significance level to see whether there is evidence that the percent guessed correctly is less than 50 % . The sample size is large enough to use the normal distribution. The standard error from a randomization distribution under the null hypothesis is SE= 0.043. 1St.John, A., "Physics of a World Cup Penalty-Kick Shootout - 2010 World Cup Penalty Kicks," Popular Mechanics, June 14, 2010.

A sample of 900 computer chips revealed that 46 % of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 50 % of the chips do not fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that do not fail is different from the stated percentage. Find the value of the test statistic.
