In hypothesis testing, such as testing the difference between two population proportions, which of the following statements is correct when the significance level is 0.05? A) Only statistics that occur with a probability of less than .95 when Ho is true are sufficient evidence to reject H, . B) Only statistics that occur with a probability of less than .05 when Ho is true are sufficient evidence to reject H,. C) Only statistics that occur with a probability of .95 or more when Họ is true are sufficient evidence to rejectH,.

You wish to test the following claim (H.) at a significance level of a = 0.005. You believe both populations are normally distributed, but you do not know the standard deviations for either. And you have no reason to believe the variances of the two populations are equal You obtain a sample - 19.1 from the first population. 7.1 from of size ni 23 with a mean of a1 You obtain a sample of size n2 the second population. 86.6 and a standard deviation of s1 20 with a mean of r2 96.5 and a standard deviation of s2 = a. What is the test statistic for this sample? test statistic = Round to 3 decimal places. b. What is the p-value for this sample? For this calculation, use p-value Use Technology Round to 4 decimal places.
