Question 1187283: The Mathematical Anxiety Rating Scale (MARS) measures an individual's level of mathematical anxiety on a scale from 25 (no anxiety) to 100 (highest anxiety). A group of researchers administered the MARS to 50 students. One of the objectives of the study was to determine if there is a difference between levels of mathematical anxiety experienced by male and female psychology students. With alpha level=0.05level of significance, is there evidence of a difference in the mean mathematical anxiety experienced by male and female psychology students?

Solution:
Step 1: State the hypotheses.(5pts)Ho:
Ha:
Step 2: The level of significance and the critical region.
Step 3: Compute the value of t test.
Step 4: Decision rule.
Step 5. Conclusion.

Ho: Male=female (score)
Ha: Male NE female
alpha=0.05 p{reject Ho|Ho true}
reject if |t|> 2.011
test statistic is a t 0.975, df=48 (from (25-1) + (25-1))
t= (x barM-xbarF)/SE the SE is sqrt (sM^2/nM+ sF^2/nF)
Conclude either reject Ho or insufficient evidence to reject Ho
