Answer True or False to the following questions: a. Suppose a 95% confidence interval for the mean score on a Stat 151 nal exam is (69.34, 74.53). Is the following interpretation of this interval correct: \"We are 95% condent that the sample mean score on this Stat 151 nal exam is between 69.34% and 74.53%." b.Atest statistic oft : 2.451 would lead to rejection of the upper tailed-test about p, at the 5% signicant level if n = 30. c. The hypothesis test H0 : ,31 = 0 vs. Ha : ,61 7E 0 is used to determine ifthere is a positive linear relationship between the predictor and response variables. d. The correlation coefficient and slope of a regression line will always have the same sign. e. The P-value for a hypothesis test with Ha : M 7E pin is equal to 0.0404 if Z = 72.05. f. If a ANOVA F-test statistic has degrees of freedom 4 and 25, there are 4 treatment groups in the data
