Studies show that the level of anxiety has increased since the pandemic. The average score before the pandemic was mu equal to 10. A sample of 76 individuals surveyed in the past three months produced M=12.8 and s=6.7. Based on the sample, was there a significant increase in the average anxiety level since the pandemic started at the 5% significance level? If the 95% Confidence Interval is (11.52, 14.08) and the value stated in the null hypothesis is 10, what conclusion can we make? (a)cannot determine (b)reject the null hypothesis and accept the alternative hypothesis (c)fail to reject the null hypothesis (d)fail to reject the alternative hypothesis
