A new steering device is supposed to increase acciu missiles missed by distances with a mean of 0.76 miles and a standard deviation of 0.04 miles. Suppose that you want Suppose the involved population is normal. What type of hypothesis test should be used for this problem? o z test o test of proportions o ttest o chi-squared QUESTION 6 For a two tailed test using test statistics z with the probability of a Type I error 0.05, what is the rejection region? O z> 1.96 or z-1.96 0 between z =-1.96 and 1.96 0 between z-1.645 and z 1.645 o z > 1.645 and z

Explanation / Answer

6. For a two tailed test using test statistic z with the probability of a type I error 0.05, the rejection region is
