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

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
