The test statistic I have (0.045) is wrong. Please help.
Consider the data set below. For a hyopthesis test, where H_0: = beta_1 = 0 and H_1: beta_1 notequalto 0, and using alpha = 0.05, give the following: (a) The test statistic t = .45 (b) The degree of freedom df = 4 (c) The rejection region |t| > 2.776 The final conclustion is A. We can reject the null hypothesis that beta_1 = 0 and accept that beta_1 notequalto 0. B. There is not sufficient evidence to reject the null hypothesis that beta_1 = 0.Explanation / Answer
Solution:-
Paired t test results
P value and statistical significance:
The two-tailed P value equals 0.5471
By conventional criteria, this difference is considered to be not statistically significant.
Confidence interval:
The mean of Group One minus Group Two equals 1.00
95% confidence interval of this difference: From -2.98 to 4.98
Intermediate values used in calculations:
t = 0.6455
df = 5
Rejection region = 3.98
standard error of difference = 1.549
The conclusion is that there is not sufficient evidence to reject the null hypothesis that beta1 = 0.
