If the test statistic is equal to 0.72 and the critical value is greater than 1, which of the following is NOT true?

If the test statistic is equal to 0.72 and the critical value

A researcher is interested in two types of protein supplements. One sample of 30 participants were each given a certain amount of Protein Supplement A. Another sample of 30 participants were each given a certain amount of Protein Supplement B. After three years, the participants had their muscle mass measured. The group that took Protein Supplement A had a mean muscle mass of M = 71 and s2=28. The group that took Protein Supplement B had a mean muscle mass of M = 70 and $2=30. Use a significance level of 5% to determine whether there is enough evidence to conclude that the group who consumed Protein Supplement A had a higher mean muscle mass than the group who consumed Protein Supplement B. Please assume the group who consumed Protein Supplement A is Group 1 and the group who consumed Protein Supplement B is Group 2. If the test statistic is equal to 0.72 and the critical value is greater than 1, which of the following is NOT true? O You would reject the null hypothesis and accept the alternative hypothesis. The corresponding p-value is greater than the alpha level. O You would fail to reject the null hypothesis. The test statistic is a t-statistic
